Adopting a modular stacked installation design to meet the requirements of large-volume air filtration, up to 3 layers can be stacked, which can effectively save space.
The box body is made of SUS 304/316 stainless steel or high-quality cold-rolled steel (electrostatic spraying), and the maximum pressure resistance is ±5000Pa.
Using quick-pressing method to compress the filter, reducing steps such as tightening bolts, making it easier to operate in the bag and ensuring the reliability of compression. Equipped with auxiliary moving device to facilitate filter replacement.
Choose glass fiber filter or PTFE high-efficiency filter, which is impact-resistant and prevents filter damage. The maximum air volume of the box filter can reach 4000CMH, and the maximum efficiency of PTFE can reach U16 (EN1822).
The single filtration system only has one high-efficiency filter; the multiple filtration system can add a primary and medium-efficiency filtration section, a chemical filtration section, an iodine adsorption filtration section, an activated carbon filtration section, and a double high-efficiency filtration section.

Our BIBO filter boxes are compatible with a variety of filters, including:
HEPA filter (H13/H14)
ULPA filter (U15/U16)
Primary efficiency filter
Medium efficiency filter
Activated carbon filter (optional)
A multi-stage filtration system can be configured according to actual applications.
The box adopts the overall full welding process, and the air tightness is tested at a pressure of no less than 2500Pa before leaving the factory. It complies with the requirements of ASME-N510, GB 50346-2011 and JG/T 497-2016, and has obtained third-party inspection reports certified by CNAS and CMA.
