Frequently Asked Questions
Q: Why is the “Deep Pleat” design better for high-volume airflow?
The deep pleat HEPA filter design utilizes aluminum foil separators to maintain pleat stability, providing a much larger surface area which allows for a rated air flow of up to 3400m³/h without increasing resistance.
Q: Can this filter withstand high-pressure conditions in large HVAC systems?
Yes. The external frame is built from thick-gauge galvanized or stainless steel, and the media is secured with specialized polyurethane sealant to prevent any structural failure under pressure.
Q: What is the benefit of the separator style for industrial dust-free workshops?
The separator-style design ensures the media remains perfectly spaced, providing high-efficiency protection and a high dust holding capacity, which significantly reduces maintenance downtime in OLED/LCD manufacturing.
Q: Is every unit tested for sub-micron efficiency?
Absolutely. We provide filters that are individually tested to meet technical standards such as 99.99% @ 0.3um and 99.9995% @ 0.12um
