Screen Door Closer Soft Closing Barrel Pneumatic Door Closer-DDPC002

Product Overview

Simple structure and low cost: Compared with hydraulic door closers (requiring complex structures such as oil circuits and seals), pneumatic simple door closers have fewer components and are easier to maintain, making them suitable for scenarios with limited budgets;

Adjustable closing speed (limited): Some products can adjust the closing speed by regulating the size of the gas release hole or the opening degree of the valve (but the adjustment range is usually smaller than that of hydraulic door closers);

Affected by temperature: The compressibility and fluidity of gas change with temperature (gas expands when temperature rises, and damping may weaken; gas contracts when temperature drops, and damping may strengthen), resulting in slight fluctuations in closing speed in different seasons or environments;

Limited application scenarios: Suitable for low-frequency use and places with low requirements for closing accuracy (such as ordinary residences, small offices, warehouses, etc.), but not suitable for high-frequency switching or scenarios with high requirements for precise control of closing force (such as shopping malls, hospitals, etc.).
