Oil-Free Silent Air Compressor

BOSI's oil-free silent air compressor series covers a variety of models for home, commercial, and industrial use. All models use high-efficiency all-copper wire motors, featuring an oil-free design that requires no maintenance, operates with low noise, and is energy-efficient and environmentally friendly.

The air tank is made of standard Q235 steel plate, ensuring safety and reliability. Some models are equipped with automatic unloading via solenoid valves, dual or multi-pipe air intake systems, and extended connecting rods for large displacement.

Available in 220V and 380V voltages, with displacement ranging from 110L/min to 1100L/min and air tank volumes from 9L to 300L. Widely applicable to woodworking nailing, painting, home decoration, automotive repair, and industrial pneumatic tool supply.

Product Features

Oil-Free Design: No need to add lubricating oil, exhaust gas is pure and oil-free, suitable for painting and precision instruments; maintenance-free, saving the trouble of oil changes.

All-Copper Wire Motor: High efficiency, long life, low temperature rise, more durable than aluminum wire motors.

Low noise: Oil-free machines are quieter than oil-based machines, making them suitable for indoor and residential use (600W models have a noise level of approximately 60-70dB).

Standard Q235 steel plate air storage tank: wall thickness meets standards, safe and reliable, and has passed pressure testing.

Automatic Unloading of Solenoid Valve (Some Models): Automatically discharges residual air in the cylinder when stopped, no load on the next start, extending motor life.

Dual-Pipe/Multi-Pipe Intake System: Improves intake efficiency, faster air intake.

Solid Casters (Some Models): Durable and not easily damaged, easy to move.

Intelligent control box (5×1.68KW): Controls the start of each cylinder separately to reduce startup current shocks.

Product Parameters

Note: Air supply time is the approximate time from 0 to maximum pressure; actual time may vary slightly depending on the environment.

Product Application

Carpentry nail driving: Oil-Free Silent Air Compressor is used with pneumatic nail guns for furniture making, wooden box sealing, ceiling decoration, etc., suitable for 50-90L models.

Spray painting: Used for car painting, furniture painting, and wall spraying. Requires a large exhaust volume (≥420L/min) and an air tank (≥50L) to ensure stable air pressure.

Home decoration: Used for pneumatic screwdrivers, pneumatic cutting machines, dust blowers, etc. Portable models of 15-30L are suitable.

Automotive repair: pneumatic wrench, tire inflator (50-120L recommended, displacement ≥420L/min).

Industrial production lines: Simultaneous air supply for multi-station pneumatic tools requires large tanks of 180-300L and high displacement, 380V three-phase power.

Laboratory/Dental: Small 9-24L silent model for instrument air supply or dental tools.

How to Select the Right Oil-Free Silent Air Compressor Model?

● By Usage Scenarios

For home DIY projects, occasional nailing, and dust blowing: choose the 9-24L (600W) model, which is portable and lightweight.

For decorators and small carpenters: choose a 30-50L (1380W single or twin cylinder) engine for good balance.

For paint booths and auto repair shops: select 60-120L (1380W×2-4 or 1680W), with an exhaust volume ≥420L/min.

Factory production lines and multiple pneumatic tools: Select 180-300L (1.68KW×3-5, 380V), large displacement and stable air supply.

● According to power supply conditions

For homes and small shops with 220V, select a 220V model (maximum 120L).

For factories and construction sites with three-phase power, select a 380V large model.

● Based on air displacement requirements

A single pneumatic nail gun consumes approximately 100-200 L/min, a spray gun approximately 200-400 L/min, and a pneumatic wrench approximately 300-600 L/min.

Choose a pneumatic displacement slightly greater than the total air consumption.

● Based on mobility requirements

For models that require frequent movement, choose those with solid casters (such as 50L or 300L). Smaller models can be carried by hand.

● Based on budget

600W small engines are economical; 1380W series offer high cost-performance; multi-cylinder large engines are more expensive but more efficient in the long run.
