Massive Dust Capacity for Extended Service Life
Our Deep Pleat Medium Filter features a high-surface-area design that provides a massive area for particulate retention. With the ability to capture up to 1120g of dust, it offers an industry-leading long service life. This High dust holding capacity reduces the frequency of filter replacements and lowers maintenance labor costs, making it a superior secondary filtration choice for general air purification in large-scale commercial and industrial facilities.
Frequently Asked Questions
Q1: Why is the F9 efficiency rating crucial for pharmaceutical and electronics industries?
-
Our High capacity F9 air filter targets fine sub-micron particles with up to 98% efficiency. In industries like pharmacy and electronics, this level of filtration is essential to prevent micro-contamination that could ruin a production batch or damage sensitive wafers.
Q2: What is the benefit of using “Gel-glue sealant” in this model?
-
Unlike standard filters that use mechanical clamping, our filter utilizes a professional gel-glue sealant to bond the media to the Aluminum alloy frame. This creates a permanent, airtight seal that eliminates “air bypass,” ensuring every cubic meter of air is thoroughly filtered.
Q3: Can this pleated filter handle the large air volumes of an industrial AHU?
-
Yes. It is specifically designed to handle a high air flow of up to 4000m³/h. The rigid separator type or reinforced pleat design prevents the media from fluttering or collapsing even under high-velocity air streams.
Q4: Does this filter work in high-humidity cleanroom environments?
-
Absolutely. The filter is rated for a max operating humidity of 80%. Combined with an anodized aluminum frame, it is highly resistant to corrosion and moisture, making it ideal for the chemical industry or humid sterile suites.
Q5: How often should I replace this filter to protect my terminal HEPA filters?
-
While it has a high dust holding capacity and a long service life, we recommend monitoring the pressure drop. Because it serves as a high-performance secondary filtration stage, replacing it on time can extend the life of your expensive terminal HEPA filters by 2-3 times.
