FIBERGLASS HIGH RATE SAND FILTERS
STARK HORIZONTAL HIGH RATE SAND FILTERS — Filament wound fiberglass filters are
designed for simple, fast installations. Filter tanks are designed for maximum operating pressure
of 75 psi with a maximum burst safety factor of 4 to 1. Gel coat fiberglass tank lining is filament
wound with continuous fiberglass strand. Lighter weight than most comparably sized carbon steel
filters. Horizontal design allows tanks to fit thru most doorways. Multi-spray head diverters and
full width laterals result in long filtration cycles and maximum backwashing effectiveness. Vessel
finished with Paracote UV resistant coating, for added protection. Available in a 36” diameter and
42” diameter single and multiple tank configurations. Stacking and custom designed systems
also available. Completely non-corrosive filters withstand the effects of pool water chemistry,
electrolysis and corrosion. 15 Year Limited Warranty. NSF Listed.
