SPECIFICATION

ASME AG-1-2019 IS THE APPLICABLE REVISION FOR THIS SPECIFICATION AND WILL BE USED WHEN EVALUATING ALL DRAWINGS SUBMITTED PER 9.B.

1. FILTER SHALL BE ASME AG-1 FILTER SIZE DESIGNATION: FC #7 PER TABLE FC-4110-1.

2. FILTER SHALL BE TESTED AND CERTIFIED TO BE NOT LESS THAN 99.97 % EFFICIENT, FOR PARTICLES OF CRITICAL SIZE 0.3 µM PER SECTION FC-5120.

3. INITIAL RESISTANCE TO AIR FLOW SHALL BE A MAXIMUM OF 1.3” W. G. AT 1500 CFM PER TABLE FC-4110-1.

4. MAXIMUM OPERATING TEMPERATURE IS 250º F PER SECTION FC-1310. MAX. R. H. IS 95% ± 5% PER SECTION FC-5140.

5. MATERIALS SHALL BE IN ACCORDANCE WITH ASME AG-1, SECTION FC 3000, CONSTRUCTION AND TESTING SHALL BE IN ACCORDANCE WITH UL 586.

CONSTRUCTION SPECIFICATIONS:

A. FRAME HARDWARE : NONE

B. MEDIUM: FILTER MEDIA SHALL BE IN COMPLIANCE WITH ASME AG-1, FC-3130. NO PATCHING OF MEDIA IS ALLOWED PER ASME AG-1, FC-4111.
