What is a gel seal HEPA filter?
A gel seal HEPA filter is one type of mini pleat HEPA filter. It adds a recess to the side or top of the filter’s outer frame, which is filled with gel sealant to form a reinforced seal. And gel seal HEPA filter uses ultra-fine glass fiber as the filter media.
Gel seal HEPA filter usually has different thicknesses, such as 70mm, 90mm, 110mm, 120mm, 140mm, etc. At the same time, the position of the gel seal is also divided into a top gel seal and a bottom gel seal (side gel seal ).
The gel sealant is blue and resembles jelly, also called jelly gel. The gel seal sealant is a non-Newtonian liquid with non-volatile, non-creeping oil characteristics, non-toxic and tasteless, etc. It has good stability at room temperature.
The gel seal HEPA filter is an ideal terminal filter for clean industrial and biological cleanrooms and an excellent companion filter for other purification equipment. The gel seal HEPA filter is easy to install, reliable, and better than other HEPA filters with the mechanical compression seal method.
Benefits of Gel Seal HEPA Filter
Gel Seal HEPA filters are a highly effective air filtration system today. They are designed to remove 99.97% airborne particles from the air, making them ideal for use in industrial or medical settings.
Gel Seal HEPA filters utilize a unique sealing system that is more efficient and reliable than traditional bag or box filters. The sealing system prevents air from bypassing the filter, which makes the filter more effective and reduces the need for frequent filter changes.
Overview of Gel Seal HEPA Filter
Design and Materials of Gel Seal HEPA Filter
The gel sealant is made of unique silicone(you can choose nonsilicone, different cost). Rubber is an elastic gel after curing, and it plays a sealing role in the gel seal HEPA air filter. It can form an airtight and airtight seal in the aluminum tank.
The gel sealant has elasticity, good resilience, good flexibility, etc., so it can achieve good sealing performance; it can absorb the strain generated by thermal expansion and contraction with no cracks to prevent air leakage.
Another point is that gel sealant can maintain the soft elasticity of the gel for a long time, and the surface does not appear to harden, cracking and other phenomena.
When the knife edge comes into contact with the gel, the gel will fit closely with the knife edge and play a sealing role. The surface of the gel will not be hardened and cracked after a long period of use and will continue to maintain a good sealing effect.
Advantages of Gel Seal HEPA Filters
Gel Seal HEPA filters offer several advantages over traditional HEPA filters. One of the most significant benefits is their ability to last longer.
The gel seal helps protect the filter from damage and prevents the filter from becoming clogged with debris. This means that the filter can be used longer without needing to be replaced, resulting in fewer maintenance costs.
In addition to their increased longevity, Gel Seal HEPA filters offer improved performance. The gel sealant helps protect the filter from moisture and other contaminants, which can reduce its efficiency over time.
High-level sealing helps ensure the filter traps and captures more particles, improving air quality.
Finally, Gel Seal HEPA filters are easier to install and maintain than traditional ones. The gel-seal material creates a waterproof seal around the filter, which makes it easier to install and remove.
How does the gel HEPA filter work?
The working principle of a gel seal HEPA filter is the same as that of other HEPA filters. The main filtration principles are the Sieve effect, inertia effect, blocking effect, diffusion effect, and electrostatic adsorption. Please refer to our other article, how air filter work.
Difference of gel seal HEPA filter compare with other HEPA filters.
The housings of gel seal HEPA filters are different.
The gel seal HEPA filter has an extra seal edge in the frame and a different filtering area than the ordinary mini pleat HEPA filter. The gel seal HEPA filter of the same size has a smaller filtering area than the mini pleat HEPA filter, and there is a gel seal edge around the gel seal HEPA filter, so the installation and sealing are different.
The sealing method of gel seal HEPA filter is different.
The air inlet or outlet of the mini pleat HEPA filter is sealed with a sealing gasket, and the gel seal HEPA filter is filled with gel sealant at the filter’s edge, which has a better sealing effect.
Price and cost are different.
Since the gel seal filter has an extra gel seal housing and the injected gel sealant is a high-cost raw material, the cost is higher when they’re manufactured, so the price of the gel seal HEPA filter is higher than other types of HEPA filter.
Gel seal is a higher sealing level than other HEPA filters.
Gel Seal HEPA filters are ideal for improving air quality in their workshop or production site. The filters are designed to trap smaller particles and provide a higher filtration efficiency than other filters. The gel seal also helps create a tight seal that prevents air from bypassing the filter and ensures that only clean air is circulated throughout the space.
With their superior performance and long-lasting design, Gel Seal HEPA filters are an excellent choice for anyone looking to improve or maintain the air quality in their environment.
