Features of Fluidizing Screens:

Cleanability – Ordinary water and detergent, high pressure steam or chemical methods may be used to clean most oil and dirt from the fluidizing material.

Moisture Resistant – Made entirely of 316 stainless steel, therefore, it does not absorb or retain moisture.  Water from condensation does not wet or permeate the metal pore structure.  If an upset condition does occur, drying is quick and trouble free.

Damage Resistant – Unlike brittle stones, stainless steel fluidizing material cannot be damaged during shipment or installation.

Direct Replacement – Designed to fit into existing castings, reusing all nuts, bolts and gaskets.

Heat Resistance – Designed for continuous operating temperatures of 1000°F and to 1200°F intermittently.

Less Downtime – Due to abrasion, heat, moisture and damage resistance product life has been estimated to be 2-4 years.

Abrasion Resistant – Constructed of Stainless Steel Wire Mesh, it produces a durable media for severe operating environments.

Lower Pressure Consumption – Less pressure drop, requiring lower air pressure, resulting in reduced blower horsepower.

Fabricating – Material can be fabricated into any shape for flyash storage silos, hoppers, etc.

Storage – 1/16” thick replacement plate is easily stored.
