This reasonably priced bag filter vessel is designed to allow high flow rates through a single reusable bag filter. It is rated at 75 gpm for clean water (for particulate-laden water and/or to extend time between cleanings, we recommend a design flowrate below 40 gpm). For higher flows, use two or more in parallel. To further extend time between cleaning, place a larger micron filter before a smaller micron filter in series. The vessel is made of polypropylene with a threaded lid, O-ring and removable internal basket for easy bag removal. This vessel has 2" FNPT inlet and outlet and 1/4" FNPT lid vent and weighs 10 lbs. Optional pressure gauges for lid vent are listed below.Bags are 6" dia x 20" length with 2 square feet of surface area. They are fitted with a Polyloc® ring, which seals directly against the filter housing, eliminating any chance of bypass.

Vessels include housing, lid, retainer basket and 2 plastic leg/foot assemblies, easily cut to required height. Optional conical base is also available. Maximum pressure is 100 psi @ 110°F. Made in USA. One-year warranty.

Differential Pressure Gauge: Designed exclusively to supplement pressure gauges used on the FV1 bag filter. It mounts on the mounting pad's vessel located on the opposite side of the inlet port. The window turns red, indicating that it is time to change. Requires a 3/16" drill to install portholes; use only the screws provided. 2" long.

filter bag

These bags can be used to remove particulate matter after sedimentation or to filter incoming water. The bags are made of monofilament single ply nylon resembling a piece of cloth. All bags are 32" long with a 7" diameter mouth and drawstring top. This allows attachment directly to your water line without the use of an adapter head.

Aquaculture filtration is a huge problem. Flowrates are high and the filtrate is delicate, slimy, organic and can easily become liquified, turning a solid waste problem into a liquid waste problem. Bag filters are very effective at removing organic particulate matter.

The monofilament type is single-ply nylon resembling a piece of cloth or window screen. The felt type is polypropylene, thick and fluffy, giving it three-dimensional filtering ability. Both are washable, but wash the felt type gently.

All bags are 32" long with a 7" diameter mouth and polypropylene ring that fits the optional Celcon® adapter (FBH) perfectly. Made in USA.


This plastic (Celcon®) adapter will thread on to 1-1/2" male thread and provide support and quick bag changes. Fits 7" diameter bags with polypropylene rings.

Zeolite is an effective means of removing ammonia. It can be used to control ammonia build-up in fresh water recirculating systems, aquaria and transport vehicles. (Does not work well in saltwater). Use 1 gram of Zeolite for every 1.5 mg of ammonia to be removed. For example to remove 1 mg/L (ppm) ammonia from 10 gallons (38 litres) of water, use minimum of 25 grams Zeolite.

A superior, high-purity, bituminous coal-based activated carbon designed for water purification. Preferred by public aquariums, research centers and government fisheries. The small particle size (approximately 1/16" to 1/8") provides a large surface area for rapid u ptake and reduces water travel distances to interior adsorption surfaces. Keeps water crystal clear. Adsorbs full range of organic contaminants, pesticides, odors, colors, chlorine, dissolved organics, ozone and many heavy metals. Carbon is dry packed. Can be retained using window screen size mesh. The 15-pound plastic bucket has a resealable lid. Approximately 0.625 / square meter of surface area per gram. Bulk density is approximately 24 lbs / cubic foot.
