Rigid-Air
General
Rigid-Air extended media surface rigid filters are
designed for use in most commercial or industrial
HVAC systems where medium to high efficiency
filtration is required.
They feature your selection of media backed with
expanded metal and pleated. The pleats are held
in place by rigid pleat separators, available in either
plastic or metal styles on 12"depth filters. 6" depth
filters feature rugged fiberboard separators. RigidAir is available in two media types: lofted fiberglass
and micro-fine synthetic with average efficiency
ranges of 50-55%, 60-65%, 80-85% and 90-95%
per ASHRAE Standard 52.1 and MERV 10-14 per
ASHRAE Standard 52.2.
These filters are especially suitable for variable air
volume systems. Operating face velocity ranges
are from 0 to 375 fpm for 6" deep filters, and from
0 to 675 fpm for 12" deep filters. Two frame styles
are available: a single header model and a box type
without header. Rigid-Air filters are UL 900 Class 2
listed. Optional Class 1 listed are available with
metal inserts and fiberglass media.

lass or Synthetic Media Rigid Filter
Bulletin PB1001-1106
The headered version should be selected for use
with the hardware listed. If the filter is to be installed
so that it protrudes upstream of the holding frame,
the box style filter is required.
Physical Data
Frame: 24 ga. corrosion-resistant steel
doubleturned flange makes a stronger frame.
Media: Lofted fiberglass or micro-fine synthetic.
Media Supports: Expanded metal grid with metal
or plastic pleat separator.
Face Grid: Horizontal and diagonal metal supports.
Header: 13/16" wide 26 ga. corrosion-resistant
steel.
Operating Limits: 180° F 100% RH%.
Actual Header or Box Filter Face Size: Nominal
size less 5/8" (e.g., a nominal 24" x 24" filter is
actually 23 3/8" x 23 3/8").
Actual Depth: 5-7/8" or 11-1/2".
Installation Considerations
Rigid-Air filters may be installed in Astr Holding
Frames, K-Trac Filter Framing Modules, Sureseal
Side Access Housings or in similar existing
hardware.
Important Features

damage during shipping and handling.
• Lofted fiberglass micro-fine or synthetic media is
held in position by upstream and downstream
plastic or metal pleat supports.
• Units are available with or without header.
• Filters are completely rigid.
• MERV 10-14

Notes:
1. PD represents clean pressure drop in inches w.g. Recommended final pressure drop for all models is 1.5" w.g.
2. Efficiency is average and is based on ASHRAE Standard 52.1 and 52.2 test methods.
3. Performance tolerances conform to Section 7.4 of ARI Standard 850.
4. Actual filter face size is 5/8" under on height and width. Actual filter depth is 5-7/8" or 11-1/2"
5. Pressure drop values shown are for synthetic media. Glass media approximately 20% greater.
6. Perfmormance values shown in this publication may be averages or estimates intended to generally represent product
styles. Contact factory for latest actual test data on specific Flanders Precisionaire models.
