Import Chair Base Comprssion Tester (Kw-Bfm-07-Qd) — Buy in Bulk from Supplier in China

The Chair Base Compression Tester KW-BFM-07-QD is a mechanical test instrument designed to evaluate the structural integrity of chair bases under controlled compressive loads. It features a 500mm air cylinder stroke and a maximum output force of 2500 kgf, with a digital display that shows real-time force readings derived from a precision pressure sensor. The system uses a manual pressure regulating valve to maintain stable force application, eliminating hydraulic variability and reducing maintenance needs.

The tester operates using compressed air at 0.5MPa with a flow rate of 800L/min, requiring filtered and dried air to prevent internal corrosion or valve clogging. Its control system includes a time relay that holds the load for 0 to 99 seconds, allowing repeatable dwell periods as defined by industry standards for furniture durability testing. The unit is built with a simple mechanical frame, minimizing moving parts and enhancing reliability in high-volume testing environments.

This tester is used by furniture manufacturers, quality assurance labs, and certification bodies to verify compliance with standards such as BIFMA X5.1 or EN 13761 for office seating. Buyers typically order in single units for in-house testing, with packaging in a steel frame crate and freight arranged FOB Dongguan. Lead time is confirmed directly with the supplier, and the unit requires no electrical power, relying solely on compressed air for operation.
