Definition: HEPA box is the terminal device in purified air supply system.
Operation Principle: The HEPA box requiring filed leak detection is provided with PAO dusty entry and upstream concentration detection mouth, and differential pressure detection mouth and lower damper based on customers’ requirements.
Advantages of ABS HEPA Box
One time injection, no leakage risk, smooth inner surface, dust-free and easy to clean.
Acid, alkali and salt-resistant, formaldehyde-resistant, VHP and O 3 Sterilize.
Flame-retardant: UL94-V0.
Flame-retardant, corrosion resistance, high intensity and other features, SGS&BV certificated.
Advantages of Plastic-spry Steel Plate
Full welding with mechanical welding machine, high efficiency.
No leakage risk.
The box is not easy to deform.
The adhesive force of the plastic spraying layer is stronger after the phosphating treatment.
