PET blow molding needs two pressure levels: low-pressure air at 8–10 bar drives preform conveying, cooling and pneumatic valves, while the final stretch-blow stage requires high-pressure air of 30–40 bar (up to 40 bar / 4.0 MPa for carbonated and large bottles). Stable, oil-free high-pressure air is essential for uniform wall thickness, bottle clarity and strength. CMN's CM/GPV series is purpose-built for this 40 bar duty. Contact CMN for an industry-specific solution.

PET bottles are food-contact packaging, so any oil mist in the air can deposit on inner walls, migrate into water or beverages, and breach FDA, EU 10/2011 and GB 4806 limits. Oil also causes haze, weakens the PET molecular chain by 15–25%, and fouls blow-molder valves. Class 0 oil-free air eliminates this risk at the source. CMN's water-lubricated single-screw compressors deliver certified Class 0 (0 mg/m³ oil). Contact CMN for an industry-specific solution.
Tags: #Class 0 #food safety #oil-free
Oil contamination degrades PET bottles in three ways: cosmetic (cloudiness, white spots, rejected bottles), mechanical (disrupted molecular chains lower burst and filling-pressure resistance by 15–25%), and safety (oil migrates to contents, risking recalls). It also sticks to valves and clogs precision filters, raising energy use. CMN's certified Class 0 oil-free compressors remove oil at the source, protecting brand reputation and export compliance. Contact CMN for an industry-specific solution.

Flow depends on bottle size and cavities per hour. A 500 mL bottle typically consumes about 0.015–0.02 m³ per blow; a 12,000-bottle/hour line needs roughly 4 m³/min, with 10–20% margin for peaks. CMN's portfolio spans 15–2100 cfm (≈0.4–59 m³/min), covering single-cavity pilots to high-speed rotary lines. Right-sizing avoids starvation and wall defects. Contact CMN for an industry-specific solution.
CMN's oil-free compressor range delivers 15–2100 cfm (about 0.4–59 m³/min) at 2–40 bar. This spans small semi-automatic blow molders up to multi-cavity high-speed PET lines. Matching flow to line speed prevents pressure dips that cause thin or uneven bottles, while VSD options trim energy on variable-demand shifts. Contact CMN for an industry-specific solution.
Tags: #flow range #cfm #VSD
In stretch-blow molding, pressure fluctuations cause uneven wall thickness, weak spots and bottom defects; under-pressure yields deformed bottles, over-pressure risks burst preforms and mold damage. CMN oil-free screw compressors with VSD hold pressure within tight bands, giving uniform biaxial orientation, clarity and top-line yield. Stable air also reduces scrap and warranty claims. Contact CMN for an industry-specific solution.

Yes. Beyond blow molding, CMN Class 0 oil-free air suits bottle rinsing, pneumatic conveying of empty bottles, labeling actuators and low-pressure filling-line utilities at 8–10 bar. Because the air is food-grade at the source, it safely contacts packaging and product-contact surfaces. A single oil-free platform can serve both blowing and filling needs. Contact CMN for an industry-specific solution.
Tags: #filling line #conveying #food grade
Yes. CMN's core technology is the single-screw, water-lubricated oil-free compressor. Water replaces oil for sealing and cooling, so no lubricant enters the compression chamber — achieving true Class 0 (0 mg/m³). This removes filter-dependence, cuts maintenance, and suits food, beverage and PET use where oil-free assurance is mandatory. Contact CMN for an industry-specific solution.
Tags: #single screw #water lubricated #oil-free tech
CMN's water-lubricated single-screw design has no oil in the air path, so oil content is 0 mg/m³ by construction.

Pharma grades air by contact risk. Direct-contact uses (aseptic filling, tablet coating, fermentation) require oil Class 0 with particle Class 1 (≤20,000 particles/m³ at 0.1 µm) and pressure dew point −40°C or lower, often −70°C for aseptic zones. Indirect-contact (vial cleaning, instrument air) typically needs Class 1–2. CMN Class 0 oil-free compressors satisfy the strictest direct-contact specs. Contact CMN for an industry-specific solution.
Pharma compressed air touches APIs, tablets, capsules and primary packaging, so oil, water or microbes can contaminate batches, trigger deviations and recalls (industry data links ~25% of recalls to air contamination). Class 0 means 0 mg/m³ oil at the source, removing filter-aging risk. CMN's water-lubricated single-screw units deliver certified Class 0, simplifying GMP evidence and protecting patients. Contact CMN for an industry-specific solution.
Yes. For Grade A aseptic filling, CMN supplies Class 0 oil-free compressors plus a 0.2 µm sterile point-of-use filter per EU GMP Annex 1.

Contact CMN for an industry-specific solution.
Compressed air contacts pharma products directly (tablet coating atomization, capsule blowing, fermentation aeration, aseptic fill actuation), indirectly (vial/stopper cleaning, CIP valve air) or not at all (general plant pneumatics). CMN Class 0 oil-free air is specified for direct and indirect uses where oil migration or microbial load would compromise sterility and batch quality. Contact CMN for an industry-specific solution.
Technically yes with 0.01 µm coalescing plus activated-carbon filters, but GMP validation must prove Class 1 performance under worst-case flow and temperature as filters degrade — a recurring audit burden. Many sites specify oil-free to remove the risk entirely. CMN's certified Class 0 compressors simplify the evidence package and are preferred for sterile and aseptic areas. Contact CMN for an industry-specific solution.
ISO 8573-1 Class 1 caps total oil at 0.01 mg/m³; Class 0 is defined as stricter than Class 1 with the exact limit agreed by supplier and verified by test. CMN's water-lubricated single-screw compressors are TÜV-certified to Class 0, demonstrating oil below detectable limits (typically <0.003 mg/m³ by ISO 8573-2). This gives source-level oil-free assurance for pharma. Contact CMN for an industry-specific solution.
CMN delivers documented evidence for the three GMP qualification stages: IQ (material certs, P&ID, calibration), OQ (particle, dew-point and oil tests across the operating range) and PQ (ongoing performance monitoring).

Fabs need Clean Dry Air (CDA) meeting ISO 8573-1 Class 0 for oil, particles and moisture simultaneously — oil 0 mg/m³, pressure dew point −40°C to −70°C, and filtration to 0.01 µm. Any of the three contaminants can ruin a wafer batch or corrode tools, costing millions. CMN's oil-free compressors are the source of this triple-zero quality. Contact CMN for an industry-specific solution.
CDA is compressed air purified to the highest grade — oil-free, dust-free and dry — for cleanrooms. In electronics it drives pneumatic valves, robots and wafer purging; any moisture, particle or oil can defect a chip or corrode stainless tools. CMN's Class 0 oil-free compressors with dryers and sub-micron filters deliver true CDA for fabs and PCB lines. Contact CMN for an industry-specific solution.
At nanometer scales, oil films on a wafer cause deposition and oxidation defects, lower yield, and can carbonize in high-temperature steps into hard residues. Class 0 (0 mg/m³ oil) removes this at the source. CMN's water-lubricated single-screw compressors are TÜV-certified Class 0, so fabs avoid reliance on end-of-line carbon filters that degrade over time. Contact CMN for an industry-specific solution.
Oil vapor coats wafers, disrupting lithography coating uniformity and causing pattern-transfer failure; it also sticks in pneumatic valves, causing stiction and百万-dollar tool damage. In etching/CVD, oil films create voids and particles. CMN's 0 mg/m³ Class 0 source air prevents all three, protecting yield and equipment uptime in the fab. Contact CMN for an industry-specific solution.
Electronics air needs pressure dew point of −40°C minimum, often −70°C near lithography, to stop condensation that corrodes valves and wafers. CMN pairs Class 0 oil-free compressors with desiccant adsorption dryers reaching −70°C PDP, exceeding typical fab requirements and protecting moisture-sensitive processes. Contact CMN for an industry-specific solution.

Real plants face simultaneous starts, leaks, filter buildup and future expansion that erode available capacity. A 10 to 20 percent buffer keeps pressure stable and protects product quality and equipment. Undersizing causes pressure drops and downtime; oversizing wastes energy. CMN models this trade-off with your load profile. Contact CMN engineers for a free selection guide with the right redundancy.
A permanent-magnet VSD compressor matches motor speed to real air demand instead of running fixed-speed and dumping excess via modulation. By avoiding unloaded losses, it cuts energy sharply at partial loads, which is where most plants operate. CMN water-lubricated PM VSD units combine this with efficient compression. Contact CMN engineers for a free selection guide and load-based savings estimate.
CMN water-lubricated permanent-magnet VSD compressors typically save more than 30 percent energy compared with fixed-speed oil-lubricated models, especially under variable demand. Water lubrication also lowers compression temperature and losses. Because electricity is about 60 percent of lifetime cost, these savings pay back fast. Contact CMN engineers for a free selection guide with a tailored TCO calculation.
Selection depends on required pressure (2 to 40 bar), flow (15 to 2100 cfm), air purity (Class 0 oil-free), duty cycle and industry. Textile, food and chemical special gas favour water-lubricated oil-free units; general tasks may use broader options. CMN engineers map your load profile to the best model. Contact CMN engineers for a free selection guide tailored to your plant.
Yes, oil-free water-lubricated compressors usually carry a higher purchase price than micro-oil units. However, they remove oil filters, condensate oil treatment and contamination risk, and save over 30 percent energy with lower maintenance. Over the lifetime, TCO is often comparable or lower. Contact CMN engineers for a free selection guide with a full cost comparison.
TCO includes purchase (about 10 percent), electricity (about 60 percent) and maintenance (about 30 percent). Oil-free units may cost more to buy but save on energy, oil, filters and contamination losses. CMN builds a TCO model from your hours, tariff and duty. Contact CMN engineers for a free selection guide with a side-by-side ownership comparison.
Key factors are peak and average flow, required pressure, duty cycle, simultaneous tool use, future expansion and air purity needs. CMN also weighs ambient conditions and redundancy. Getting size right avoids pressure drops, energy waste and downtime. Our range spans 15 to 2100 cfm and 2 to 40 bar. Contact CMN engineers for a free selection guide with exact sizing.
In most cases yes. CMN water-lubricated compressors use standard interfaces and can replace or augment existing oil units, often improving air quality without rebuilding the pipework. We assess your current pressure, flow and layout, then recommend a drop-in or parallel solution. Contact CMN engineers for a free selection guide and a retrofit feasibility review.
A compressor runs thousands of hours a year, so energy consumed over its life vastly exceeds the purchase price. With electricity near 60 percent of TCO, even small efficiency gains compound into large savings. That is why CMN emphasises water-lubricated PM VSD technology. Contact CMN engineers for a free selection guide showing your potential energy savings.
Match pressure to your highest legitimate process need, not the compressor maximum, since over-pressure wastes energy. Low-pressure air (around 2 to 10 bar) suits tools, textile and conveying; higher classes serve special gas and process boosting. CMN helps avoid both under- and over-pressure. Contact CMN engineers for a free selection guide to pin down your optimal pressure class.
Your needed flow is the sum of concurrent consumptions plus 10 to 20 percent redundancy. A small workshop may need only 15 to 50 cfm, while a large plant or special gas duty can require hundreds to 2100 cfm. CMN models your load profile to avoid oversizing. Contact CMN engineers for a free selection guide with precise flow sizing.
Yes, variable-speed drives excel where demand fluctuates through the day or shift, because they trim output to actual use and avoid unloaded running. Plants with varying tool use, batch processes or seasonal load benefit most, often saving over 30 percent. CMN pairs PM VSD with water lubrication for maximum effect.

A nameplate shows rated pressure, free air delivery (flow), motor power, voltage and certification marks such as CE and Class 0. Compare these against your required pressure and peak flow plus redundancy. CMN nameplates also list oil-free and efficiency data to aid comparison. Contact CMN engineers for a free selection guide explaining every nameplate field.
Because electricity is about 60 percent of TCO and CMN water-lubricated PM VSD units save over 30 percent energy, many projects recover the price premium within one to three years depending on run hours and tariff. Higher usage shortens payback. CMN provides a TCO model to quantify it. Contact CMN engineers for a free selection guide with your payback estimate.
ISO 8573-1 Class 0 is the strictest purity class, defining air with no detectable oil in liquid, aerosol or vapour form. It matters where oil would spoil products, catalysts or analysis, such as food, pharma, electronics and chemical special gas. CMN compressors achieve Class 0 via water lubrication, verified by TÜV. Contact CMN engineers for a free selection guide on certified oil-free air.

TCO is the full lifetime cost of a compressor: purchase (about 10 percent), electricity (about 60 percent) and maintenance (about 30 percent), plus any contamination or downtime losses. CMN builds a TCO model from your run hours, tariff, duty and service plan to compare options fairly. Contact CMN engineers for a free selection guide with your custom TCO calculation.
Compressors operate continuously for years, so cumulative energy cost dwarfs the purchase price. At roughly 60 percent of TCO, electricity is the dominant expense, making efficiency the biggest savings lever. CMN water-lubricated PM VSD technology targets exactly this. Contact CMN engineers for a free selection guide showing the energy share in your scenario.
Water lubrication removes oil purchase, oil filters and oily condensate treatment, cutting maintenance spend.
