Cleanroom PRE-FILTER

Long Time Electrets Pre Air Filter Features:

* Fibers with particular features can generate permanent electrets during the manufacturing process. Filter can be used for a long period of time because there’s long lasting electrets suction and high particle efficiency.

* When filter is in operation, particles can be accumulated and equally disperse on the fiber cover. It would prevent uneven exceed pressure from particle and can last for a long term of usage, which is more durable than other general filters.

* The nonwoven material of filter has special texture from thin to dense that can disperse particle attachment evenly.

Cleanroom MEDIUM FILTER (PH)

STANDARD SPECIFICATIONS

PH series filters provide medium to high efficiency performance and extended service life.
FOUR EFFICIENCIES are available: 45%, 65%, 85% and 95%.
While the PH is a replaceable filter, its completely rigid construction assures structural and performance integrity throughout its entire service life.

PH filters are ideally suited for variable volume systems. Being totally rigid in construction, performance is not affected by normal changes in heating, ventilating and air conditioning air velocities, or fan shutdown, and the filter’s configuration is not altered by accumulation of dirt.

PERFORMANCE
All PH filters may be operated at velocities up to 500 fpm. Underwriters’ Laboratories rating is Class 2.

XL/PH – Rated on ASHRAE
52-76 Test Standard at 40~45% efficiency.
The arrestance rating on that Standard is 96%.

15/PH – Rated on ASHRAE
52-76 Test Standard at 60~65% efficiency.
The arrestance rating on that Standard is 97%.

100/PH – Rated on ASHRAE
52-76 Test Standard at 80~85% efficiency.
The arrestance rating on that Standard is 98%.

200/PH – Rated on ASHRAE
52-76 Test Standard at 90~95% efficiency.
The arrestance rating on that Standard is 99%.

DERATING FOR ENERGY CONSERVATION
The PH series may operate at lower velocities to effect reduction in energy consumption. Graphs are available from Farr company indicating relative service life and pressure drop vs. airflow.

Cleanroom HEPA FILTER

PERFORMANCE
Filters are individually tested for efficiency using 0.3 micron Dioctylphthalate smoke. The results are indicated on each filter along with air flow and pressure drop.

Filters are tested for air flow resistance and DOP (dioctylphthalate) smoke penetration (a mean particle diameter of 0.3 microns) by measuring upstream and downstream concentrations of the smoke by photometer. Each filter is individually tested and certified.

BASIC CONSTRUCTION:

Frame:  

Woodboard, metal or plastic as specified.

Media:  

Highly efficient microfiberglass paper folded over corrugated separators of aluminum which prevent the media from nesting and channel air flow for lowest possible resistance.

Gasket:  

Sponge neoprene or other specified materials.

Adhesive:

fire retardant sealant.

DESIGN AND CONSTRUCION:
A continuous sheet of Micro Glass Fiber Paper is pleated into closely spaced pleats, each pleat supported by a corrugated separator.
The filter pack is enclosed in a frame of wood board or metal. Plastic can be specified for special construction.
The filter is sealed into the frame using a Fire retardant adhesive.
