We make 5 series oil-cost-free CZPTs, HB, Hd, DE, HW, HY. High definition and DE series oil-cost-free CZPTs use DURR and FIAC heads. HY, HW and HB use our own Hongrun heads.

Qualities of Hongrun oil-free CZPTs:
Oil-cost-free: Do not require any lubricated oil, output air with out any oil, protect air appliances.
Antirust tank: The inside of tank is coated with spraying, which assures clean air and fights corrosion.
CZPT adjustment: Substantial good quality strain change used to manage the energy of CZPT routinely by adjustment of pressure degree.
Easy operation: Employing straight when connecting with electricity.

Simple maintenance: No want any lubricated oil.
Reliable good quality: Apply one section and 3 phases motors, lower faults charge, immediate existing piston, increase longer daily life.
Can be outfitted with silence box, drying system, filtering program, drying diploma can achieve to -forty degree, filtering accuracy can reach to .01μ M.
Safety employing: Air compressors outfitted with self-defense device, when voltage is not steady or have other abnormal issue, can self-shield, computerized reset when temperature is reduce.

In addition to widespread traits, HY and HW collection have specific tremendous -silent design and style that can minimize noise air pollution. Meanwhile, HW sequence is far more tremendous power-conserving than other series, innovative design and style, higher quantity of air era, lower power usage, volume of air technology is 1.5-2 occasions than common piston compressors underneath identical electrical power and pressure.
All series can be picked to be outfitted with cabinets.
