Air Tightness

The enclosure features a fully welded construction with standard pressure resistance of ±3kPa. Prior to shipment, each unit undergoes air tightness testing at a pressure no less than 2.5kPa. Complies with GB 50346-2011 and JG/T 497-2016 requirements, and has obtained third-party inspection certification.

Protective Sealing Bag

Each access door of the bag-in/bag-out filter enclosure is equipped with a protective bag approximately 2m in length, complete with a full set of drawstrings and safety belts. The premium model includes two internal gloves for convenient operation. Filter replacement occurs within the protective bag, preventing gas inside the enclosure from contacting the external environment, thereby safeguarding both operators and the surrounding area.

Optional Filter Stages

Single-stage filtration features only a high-efficiency filter. Multi-stage filtration options include pre/medium-efficiency filtration

Sections, chemical filtration sections, activated carbon filtration sections, dual HEPA filtration sections, etc. Filtration stages can be customized as required.

Installation Methods

Standard installation is horizontal. Vertical or other configurations are available based on site conditions. Series connection of units extends gas residence time within the enclosure. Rain shelters can be provided for outdoor installations.
