Silent Oil Free Piston Compressor

The oil-free silent piston compressor is an air compressor that adopts oil-free lubrication technology and operates with extremely low noise levels. It requires no lubricant addition, delivers pure compressed air, and through optimized design reduces operational noise (typically below 65 decibels, equivalent to normal conversation volume).

Power：0.55 kw-1.5kw

Features

silent design

Through technologies including intake filter, low speed motor, and vibration-damping structures, noise levels are controlled between 50-65 dB, making it ideal for quiet environments (e.g., laboratories, offices).

high energy efficiency

Direct driven design,reduces energy consumption by 20-30% compared to traditional belt-drive models.

oil free technology

The piston assembly incorporates self-lubricating materials (e.g., PTFE) to prevent oil contamination, ensuring 100% oil-free air output that complies with stringent purity requirements for medical and food-grade applications.

high portability

Some models feature compact size and lightweight design (e.g. household units approximately 10-20kg), with built-in wheels for easy mobility.

low maintenance cost

Eliminates lubricant changes, reducing maintenance costs - only requires periodic cleaning of air filters and cooling vents.

core technology

Self-lubricating material piston ring

PTFE (Polytetrafluoroethylene)-based composite materials (piston rings): Incorporates carbon fiber, graphite, and ceramic particles to enhance wear resistance and thermal conductivity.

Exhibits ultra-low friction coefficient (0.02-0.1) and high temperature resistance (up to 250°C/482°F)

Anodized coating (cylinder)

Significantly improves cylinder wear resistance, with tested performance remaining robust after 1,500 hours of operation.

Silencing technology

Low-speed motor: maintains startup and temperature rise performance while reducing operational speed, with full series CE certification.

High-efficiency intake filter: Folded paper filter element ensures noise reduction without intake loss, with extended inlet for further sound attenuation.
