Core Selling Points
Pure water replaces lubricating oil inside compression chamber.Zero‑oil‑pollution output comply with ISO8573‑1 Class0 standard avoid product quality accidents and recalls caused by oil‑contaminated airalex-compr Perfect for food‑contact pharmaceutical semiconductor clean‑room production.
Water absorbs compression heat rapidly to realize near‑isothermal compression. Better heat dissipation vs traditional dry‑type oil‑free screw compressor. Optional VSD variable frequency drive automatically adjusts capacity following real‑time air consumption cuts your electricity operating cost significantlyQuanwei
No compressor oil no oil filter no oil separator required. Save expenses on lubricant purchasing replacement and waste‑oil disposal. Core contact parts adopt anti‑corrosion material extend unit service life and reduce downtime lossalex-compr
Optimized water‑injection rotor profile and circulating water cooling system keep stable working temperature even under non‑stop full‑load running. Suitable for factory continuous‑production scenarios.
Equipped with high‑definition touch‑screen controller real‑time display of pressure, flow temperature, running hours. Auto fault alarm remote monitoring optional easy for on‑site operators and plant management.
Full spectrum from small‑power lab unit to large‑power heavy‑industrial model: power 7.5‑355kW, pressure up to 4.0MPa. Support custom voltage, special connection OEM branding for global partners.
We are original manufacturer instead of trading company. Rich project experience for worldwide markets. We warmly welcome overseas distributors system integrators to become our authorized global agents get competitive factory‑direct price and full technical support.
Is water‑lubricated compressor really 100% oil‑free?
Yes. In compression cavity we use purified water for lubricating, sealing and cooling no lubrication oil is injected into compression chamber. The output compressed air reaches ISO8573‑1 Class 0 oil‑free grade no oil contamination risk from source
What kind of water should be used for this water‑lubricated compressor?
RO reverse‑osmosis purified water / de‑ionized water is required. Tap water with high hardness will cause scaling and shorten air‑end service life. Please follow our operation manual for water‑quality requirements
How does it compare with dry‑type oil‑free screw compressor?
Water‑lubricated model adopts single‑stage compression with near‑isothermal cooling. It has higher energy efficiency, lower noise, fewer wearing parts, and lower maintenance cost. Dry‑type oil‑free usually uses two‑stage compression with higher purchase and running cost
Can WPM unit run 24‑hours non‑stop?
Yes. Our circulating water cooling system is designed for continuous heavy‑load working. For 24/7 production plants, regular water‑filter maintenance is required according to service schedule.
Do you support OEM & ODM service? Can I become your agent?
OEM / ODM including logo custom voltage custom is supported. We are actively recruiting global agents & distributors. Please send inquiry to get agent policy and price list.
What is your lead time?
Standard models: 20‑30 working days. Custom‑special‑spec models: 35‑45 working days subject to order confirmation.
What after‑sales support can you provide for overseas customers?
We supply English operation manual video guidance for installation & maintenance spare‑parts supply. Online technical support available. Local agent partners can provide on‑site service in target markets.
