No partition structure
Gel seal HEPA filter is significantly different from traditional partition filters. Their filter material is made of glass fiber and forms a continuous wavy pleated structure through origami technology, so there is no need for the support of aluminum partitions. This design not only expands the filtration area, but also effectively reduces wind resistance and improves dust holding capacity.
High efficiency (HEPA level)
Filtration efficiency for 0.3 micron particles ≥99.99% (according to EN 1822 standard).
Liquid tank sealing technology
By applying polyurethane gel on the edge of the filter material to form a liquid sealing tank, the liquid tank is tightly fitted with the installation frame during installation to form an airtight seal to prevent leakage of unfiltered air.
Product Features
Advantages
Liquid tank sealing technology, PU gel liquid sealant fills the frame tank, and the sealing reliability is close to 100%.
Lightweight and easy installation.
Higher filtration efficiency and better cleanliness performance.
Compact structure, saving space and cost.

Application
H14
1. High risk biosafety: BSL-3/4 level laboratories, negative pressure isolation wards (such as highly infectious pathogens such as Ebola).
2. Key pharmaceutical production: sterile injection filling line (GMP Class A clean area), vaccine production core area.
3. Semiconductors: nano-chip manufacturing (Class 10-100 clean room), photolithography machine environment control, liquid crystal panel (OLED/LCD) dust-free workshop, etc.
4. Nuclear industry: radioactive particle filtration.
H13
1. Pharmaceutical industry: GMP clean room (Class B, Class C area), oral solid preparation workshop.
2. Hospital: general operating room, ICU ward, sterile dispensing room.
3. Electronic manufacturing: LCD panel assembly, packaging test (Class 1000-10000 clean room).
4. Laboratory: general microbiology laboratory, PCR laboratory (non-high-risk pathogens).

Regular Inspections
Inspect the filter frame, liquid tank, and sealing surfaces for damage, deformation, or rust.
Check the sealant in the liquid tank for leakage, drying, or deterioration (normally, it should be a uniform liquid with no stratification or solidification).
Inspect the sealant in the liquid tank at the joint between the filter and the mounting frame for bubbles or gaps.
The above situations will cause unfiltered air leakage, affecting the normal working efficiency of the gel seal HEPA filter and need to be replaced in time.
