Superflow 2K Performance

The Superflow 2K filters offer HEPA efficiency at an ultra low pressure drop for HVAC systems supplying air to critical areas.

Figure 1 illustrates the Superflow 2K pressure drop as a function of air flow rate for gasket seal and gel seal designs.

Superflow 2K Selection

All products have a rated overall efficiency of 99.99% at 0.30 µm and a maximum pressure drop of

1.0 inch w.g. at the rated flow. Specify the following:

Material Types:	8	= Galvanized
	5	= Aluminum
	3	= Stainless Steel
