Aluminum Casthouse

Low Phosphate is not No Phosphate

Our Patented CS-X Non PBA (Phosphate Bonded Aluminum) Filters provide improved quality of final filtered metal and are environmentally safer.

Know The Difference

 Did you know that phosphate bonded ceramic foam filters can result in…

Enviromentally Dangerous

Toxic Gas Release

The release of phosphine gas – a neurotoxic and highly flammable gas.

Higher Scrap – Damaged Toolings

Poor Casting Quality

Edge crushing and filter particles released into the downstream metal.

Low Phosphate is not the same as NO Phosphate. 


How Safe Are Your

Filters For You?

Magnesium phosphide reacts with moisture in the air to form phosphine gas

According to the 2009 U.S. National Institute for Occupational Safety and Health (NIOSH) pocket guide, and U.S. Occupational Safety and Health Administration (OSHA) regulation, the 8 hour average respiratory exposure should not exceed 0.3 ppm. NIOSH recommends that the short term respiratory exposure to phosphine gas should not exceed 1 ppm. The Immediately Dangerous to Life or Health level is 50 ppm

The Original Innovator Of Ceramic Foam Filters

50 Years of  Innovation is no accident.

SELEE pioneered the use of ceramic foam technology in metal filtration. As a result of this commitment to innovation, SELEE remains consistently at the forefront of the latest developments in filtration, melt treatment and transfer processes for molten metals of all types.

Introduced by SELEE in the mid-1970s, and redeveloped with CS-X®, the SELEE Ceramic Foam Filter continues to be the standard for aluminum filtration in cast houses all over the world.

The filtered metal is significantly cleaner. Cleaner metal results in higher quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom line profit.
