Pharmaceutical Gel Seal HEPA Filter
These two gel types provide a physically compliant,
air tight seal between the HEPA filter frame and its housing.
Both contain similar characteristics in terms of elasticity, surface tack and softness and will perform the basic job of sealing HEPA filters to the air delivery system.
However there is a wider acceptance of Silicone gels in general HEPA applications.
Silicone gels are produced by several major corporations and are included in a range of electrical, electronic, vibration damping and sealing applications. They are generally more resistant to chemical breakdown and enable higher usage temperatures; but are also relatively high in cost, and may suffer cure inhibition when applied directly to some incompatible substrates.
Polyurethane gels are not commonly used by many HEPA filter manufacturers. Although they are relatively low cost and offer fairly good chemical resistance, commonly cited disadvantages include high moisture sensitivity of the unreacted components resulting in a limited raw material shelf-life, less resistance to chemical breakdown and incompatibility with certain substrates that may result in cure inhibition.

HAOAIRTECH air filter hepa has been tested in various aspects. It has passed the anti-aging test (ASTM D573), tearing strength (SATRA TM30), seaming strength (SATRA TM180), colorfastness to rubbing (AATCC 8), etc. Customers' logos can be printed on this product
During the design of HAOAIRTECH air filter hepa, many factors have been incorporated. They involve motion mechanics, the study of materials, balance & pressure of motion, and so forth. It has been designed to provide maximum coverage, comfort, and flexibility
HAOAIRTECH portable hepa filter has been strictly monitored during production. It has been inspected with regards to cracks, discoloration, structural safety, slip resistance, and biomechanical comfort. It can be customized with metal ions like copper ions to increase effectiveness
HAOAIRTECH air filter hepa must go through the required physical tests. They include abrasion testing, adhesion testing, colorfastness testing, dimensional stability testing, hardness testing, and thickness testing.
Quality inspections for HAOAIRTECH air filter hepa are implemented in our production process. They cover strength and durability testing (e.g. puncture resistance and tear strength), Eco testing (formaldehyde content analysis), etc. It has been designed to provide maximum coverage, comfort, and flexibility
We have built a strict quality control system to fully ensure its quality. It is designed and manufactured in accordance with China GB, GB/T, and GHZB standards
