Performance Specifications


	Filter Size Rating:		Size rating is the low end of the size range that is filtered or blocked by the filter. A 10μm (micron) filter, for instance, would block any particles or droplets 10 microns and above in diameter.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

	Maximum Air Volume:		Maximum airflow rated to pass through filter.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Maximum Inlet Pressure:		Maximum rated pressure for regulator supply.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Operating Temperature:		Full required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
