BIS285 - The BIS British Imperial housing is manufactured from polished stainless steel. It can accommodate two
IMP700 ceramic candles. The upper chamber is filled with water which then gravity feeds through the ceramics into the lower chamber. An easy to
use spring loaded spigot is used as the outflow tap. This system is holds 3 gallons of processed water.
Doulton IMP700 2 stage Imperial "Super Sterasyl" candles are one of the recommended cartridges for gravity systems. (note: CU1200 UltraCarb candles are designed for pressure fed systems. They will work in gravity fed systems but the flow rate is reduced).
This unit is simple to assemble and requires no specialty tools (screwdriver only). The outflow spigot and upper chamber lid knob are the only items to be installed by the purchaser. Assembly time is approximately 5 minutes. Detailed instructions are provided.
NOTE:
This is also an outstanding, affordable, EMERGENCY WATER SUPPLY system. It may be stored un-used in homes, businesses, automobiles, etc. indefinitely.
It is always ready for use! (see our full line of gravity fed systems in our color photo
catalogue)
