The ZPQ  air filter regulator is an indispensable auxiliary device in industrial automated pneumatic control systems. Its primary function is to filter and purify the uncleaned compressed air from the compressor station, removing moisture, oil droplets, and solid particulate impurities, while regulating the higher supply pressure to a stable working pressure required by the process. This device integrates the three functions of filtration, pressure regulation, and stabilization into one unit, effectively protecting downstream valve positioners, solenoid valves, and pneumatic actuators from contamination and pressure fluctuations. Air filter regulators are widely used in instrument air supply systems across petroleum, chemical, power, and metallurgical industries.

1.High-efficiency filtration:Equipped with high-performance sintered fiber or metal filter elements for superior interception. It effectively removes condensate and fine dust to ensure the purity of instrument-grade air.
2.High-precision regulation stability:Utilizes a precision balanced regulation structure to ensure a stable output with minimal influence from flow fluctuations. Excellent overflow characteristics allow for timely release of downstream overpressure.
3.Compact and lightweight structure:The die-cast aluminum alloy housing provides small dimensions and light weight. The integrated design reduces external leak points and facilitates installation in confined spaces near actuators.
4.Durable and corrosion-resistant:The shell surface is treated with anti-corrosion coating, and internals are made of wear-resistant materials. Bowls are available in reinforced polycarbonate or aluminum alloy to suit various industrial environments.
5.Pressure setting lock function:The adjusting knob features a self-locking mechanism. Pressing the knob after setting the target pressure prevents drift caused by accidental contact or vibration on-site.
6.Multiple configurations:Offers various connection sizes (e.g., 1/4" to 1/2" NPT/G) and pressure ranges. Manual or automatic drain options are available to meet specific maintenance requirements.
7.Clear instrument display:Standardized with a clear pressure gauge for real-time monitoring of output pressure. The gauge port orientation can be adjusted based on piping layout.
8.Low maintenance cost:Filter elements and seals feature a modular design. Replacement and cleaning do not require dismantling the main piping, significantly reducing downtime.
