Frequently Asked Questions
Q1: What is the main advantage of “Gel Seal” over traditional gasket filters?
The liquid seal HEPA filter uses a jelly gel sealant that flows into the frame’s groove, creating a permanent, elastic, and 100% airtight barrier that eliminates the risk of air bypass often found in traditional mechanical gaskets.
Q2: Can this H14 Gel Seal filter handle high humidity in food plants?
Yes, the anodized aluminum alloy frame and high-density fiber glass paper are designed to perform stably in up to 80% humidity, making it ideal for aseptic bottling and dairy processing.
Q3: Is the gel used in the filter non-volatile and safe for labs?
Absolutely. We use a high-adhesion, non-volatile polyurethane gel that remains stable up to 80°C, ensuring no chemical off-gassing in sensitive biological safety labs.
Q4: Does the low resistance feature impact the filtration efficiency?
No. Our low resistance ($\le$220Pa) is achieved through optimized hot-melt separator technology and pleat density, ensuring you get certified H14 to U16 efficiency while significantly reducing HVAC energy costs.
Q5: Are these filters compatible with standard FFU knife-edge frames?
Yes, the dedicated gel-groove design is precision-engineered to match standard knife-edge ceiling grids and integrated HEPA supply units for seamless installation.
