The box is welded with high-quality SPCC(white epoxy coating) or stainless steel plate. Using a special anti-leakage design, combined with special sealing of all weld sites and 100% leak test, the module is leak-proof.

The diffuser can be fixed through a variety of fixed options, replacement of filter can be fixed through a variety of fixed options, replacement of filter can be done directly at the bottom of the ceiling grid, making installation and removal easy.

The module structure is compact and lightweight and can be directly suspended or mounted on the ceiling T-grid. Airflow pipe can be connected directly through top access or side access with either circular or rectangular inlet.

The filter frame is made from stamping an entire piece of steel palte to ensure that the filter gasket contact surface smoothly, effectively preventing air leakage.

Unique compression device design: The filter frame is supported by compression devices found on all four sides of the frame. For easy replacement of HEPA fiter , all the filter compression devices can be freely installed into the compression device bases welded onto the sides of the frame.

In site detection can be carried out using in the existing cleanroom by introducing and distributing aerosol or atmospheric dust . Pressure testing capabilities can easily determine the resistance of HEPA filter, determining the filter lifespan
