Proprietary patent "2 vent holes" construction design, keep the outside of oil seal at atmospheric pressure. During the unloading period of the compressor, the compression chamber is changed into a negative pressure area. One more vent hole can sucked air to avoid lubricating oil entering compression chamber through oil seal. Ensuring the absolute oil-free compressed air even has been running unloading for a long time.

Unique intake and exhaust system

Air filter, motor and cooling system are independent passage, and suctions cold air from lower position, exhausted hot air from top. On the one hand can ensure that air can entering the unit from the most reasonable position, excellent heat dissipation greatly reduces heat consumption. On the other hand can prevent noise come out from the air inlet channel. Independent air inlet box and channel design makes intake pressure drop to minimum. The external suction position ensures the intake air temperature is much lower than internal of unit and improves compression efficiency

Big and low pressure drop cooler

Increase the cooling area not only provide high heat exchange efficiency but also increase service life by adequate spare capacity. More energy saving with low pressure loss. Plate-fin-tube cooler construction, cooling water goes inside pipe and compressed air goes by the shell, easy to clean. Drawer type design makes convenient to maintenance and installation.

Low vibration and noise

Compressor had been dynamic balance before assemble makes low vibration and steady running. Special design of perforated plate silencer and resonant silencer reduced 15 dB(A) of upper 1KHz noise. And with high efficiency blind shutter makes unit noise below 75 dB(A)
