High Efficiency Particulate Air Filter

The High Efficiency Particulate Air Filter is the terminal filtration element installed at the clean side of a purification air-handling system, removing fine particulates from the supply air before that air enters the controlled room. Its housing is formed from aluminum alloy selected for long service: the frame stays rigid and dimensionally stable under repeated pressure-differential cycles and does not deform or sag the way lighter housings can. The filter media is melt-blown fabric, the same material used in medical-grade masks, and the pleated media is set by a hot-melt bonding process that holds each pleat at a uniform spacing and prevents media migration or channeling over time. Per the material specification, the media delivers a 99% filtration efficiency for bacteria capture while keeping airflow resistance low. The enlarged internal flow chamber lets incoming air spread across the media more completely, so pollutants are captured thoroughly rather than bypassed along the edges, and the larger dust-holding volume extends the interval between change-outs. The result is a low-resistance terminal element with a high capture-to-pressure-drop ratio and a long working life in continuous ventilation duty.

For buyers who need a standard terminal HEPA element as a matched line item for cleanroom projects, the value is consistency rather than engineering novelty. Jinye builds this filter within its mature air-purification product range, so frame sizes, housing finish and media configuration stay repeatable order after order - which matters when a project requires several identical replacement elements or when an air-handling unit expects a filter that drops into a standard terminal slot. Because each unit passes pre-delivery inspection and ships EXW, procurement teams can treat it as a recurring component they reorder without a fresh engineering negotiation, and volume orders qualify for tiered pricing. Sizes can be adapted to an existing holding frame within the current range, but the element is not redesigned from scratch, so lead time for standard configurations stays around ten working days.

• Pharmaceutical and hygiene cleanrooms. Installed at the terminal supply of purification air-conditioning systems, the low-resistance, high-capture media protects controlled environments in drug manufacturing and health-care clean spaces where supply air must meet controlled cleanliness levels.
• Electronics and precision manufacturing. The enlarged internal chamber spreads airflow thoroughly across the media, capturing fine dust before it reaches sensitive assembly areas that are vulnerable to particulate contamination.
• Chemical and general cleanroom ventilation (Class 1,000 / 10,000 / 100,000). The rigid aluminum housing holds its shape under continuous system pressure, and the melt-blown media captures bacteria-level particulates, suiting terminal filtration across the chemical and industrial purification air-conditioning range.

Frame sizes and configurations can be adapted within the existing mature product range (320 / 484 / 630mm series), and dimensions are discussed per project. Jinye does not develop brand-new filter designs outside its current technology.

Shipped EXW (ex-works). Each filter passes a pre-delivery inspection before dispatch. Units are packed in standard protective packaging for transport. Jinye does not arrange ocean freight, air freight, courier or DDP/CIF delivery.
