STJH-WASHABLE-SYNTHETIC-PRE-FILTER-COARSE55

Washable Synthetic Pre-Filter ISO Coarse 55%

A 14 mm progressive synthetic mat that balances washable service, coarse arrestance and moderate velocity.

14 mm progressive nonwoven
ISO Coarse 55% classification
Reusable first-stage medium

Giới thiệu Sản phẩm

The 14 mm medium uses a progressive polyolefin nonwoven to collect coarse particles through more of its depth. Rated ISO Coarse 55%, it operates at a nominal 1.5 m/s media velocity with a 30 Pa initial drop. This middle grade is intended for routine cleanroom make-up air where repeated cleaning is useful but the very open 8 mm mat does not provide enough arrestance.

Các tính năng chính

Balanced washable grade

The medium combines more coarse-particle capture than the 30% version with less depth than the 20 mm high-arrestance option.

Depthwise loading

Progressive fiber density distributes captured debris through the mat instead of concentrating it only at the inlet face.

Moderate velocity selection

A 1.5 m/s nominal media velocity suits general make-up-air duties when filter area is correctly sized.

Applications

Used at cleanroom make-up-air intakes, utility AHUs and controlled production support systems that require a washable coarse stage. It provides an intermediate choice between high-velocity debris screening and the thicker ISO Coarse 75% mat.

Solutions for Your Application

The lightest washable mat passes too much coarse atmospheric dust.The 14 mm progressive medium raises the classification to ISO Coarse 55% while retaining reusable service.

Cleaning compresses the fiber bed and changes airflow.Use low-force washing, avoid wringing and reinstall only when the mat has regained its dry shape.

Các tùy chọn có sẵn

Finished dimensions, perimeter support, removable frame and spare-media format can be selected for the existing AHU rack.
