MM 935 - 935 Multi Media Crushed Plate Glass with Manual Valve


935 Multi Media Crushed Plate Glass with Manual Valve
These Filters are designed to filter sediment down to an unbelievable 5 microns. The tanks are rated to 150 PSI pressure and 35 LPM flow rate

The Crushed Plate glass tank media has many outstanding advantages over common granular filter sands and multimedia used for suspended solids reduction. The glass granules allow for reduction of dirt, silt and organic matter suspended in water by bridging, straining and adhesion. The smooth fired glass surface allows no place for Algae to grow and provides a high surface area for efficient reduction of suspended matter. Utilizing deep bed filtration can typically reduce suspended solids down to the 5 micron or less range.

Filter-Ag Plus®’ structure typically creates less pressure loss through the filter and allows deeper sediment penetration into the bed for higher sediment loading and longer filter runs. The deep bed filtration capacity of Filter-Ag Plus® prevents a rapid buildup of head loss and blinding problems that are associated with typical sand filters. The longer filter run times reduce backwash frequency, which provides conservation of water. This ideal combination of particle shape, texture and porosity make it a good choice where quality water filtration and water conservation are important.

Substantial savings can be realized when designing a system using Clack Filter-Ag Plus®. Its low pressure drop, high service flow rates and high bed loadings combined with lower backwash frequency allow economy in equipment downsizing and reduced pumping requirements. Its low density also saves on handling expense and shipping costs.

Clack Filter-Ag Plus® can be applied to systems designed for either pressure or gravity flow. Because of its unique physical characteristics, Filter-Ag Plus® can be used to replace multimedia (graded density) filter designs.


  1. - Deep bed filtration results in superior water quality and reduces the load on downstream equipment.

  2. - High sediment removal capacity results in longer filter runs, with a substantial savings in backwash water and time out of service.

  3. - High service flow rates result in lower equipment costs and a savings in space.

  4. - Reduced shipping cost due to lighter weight/cu.ft.

  5. - Replacement of multimedia with Filter-Ag Plus in existing installations may increase filter capacity.

  6. - Filter-Ag Plus is an all-natural, environmentally safe product.
