Paper Only Filter Holders

Paper Only Filter Holders

The following filter holders are used for the collection of particulate from the air (in-line or open faced) taken with either high or low volume pumps. Choosing the correct filter holder is dependent on three factors: 1. Type of Pump (Rotary Vane or Centrifugal Fan), 2. Filter paper dimensions (i.e.: 2" dia., 47mm dia., 8" x 10" , etc.…), and 3. Type of connecting fitting (i.e.: 3/8" male quick disconnect or thread type). All of
HI-Q's filter holders are machined from 6061-T6 Aluminum (unless otherwise specified) and anodized Black, Gold or Blue depending upon the filter type. Add a "-SS" to unit model number for Stainless Steel holder construction.
