This vehicle loading-capable infiltration filter shaft has a 3 stage cleaning process to ensure high quality water (Coarse Filter, Fine Filter and Sedimentation Zone) to ensure optimum infiltration performance. Filter shaft retains impurities that could have a negative effect on infiltration performance.

Variable installation depth from 22" - 41" when using a telescopic dome shaft. A maximum flow rate of 88 gallons per minute (GPM) can be achieved with a 4" input and output or 250 gallons per minute (GPM) with 6" connections.
