With the Hydra Rainmaster Trio three stage filter, any facility that harvests rainwater can purify rainwater and repurpose it for utility. The Hydra Rainmaster Trio is a three-stage self-cleaning filter. The first stage filter includes a stainless-steel net cartridge of 90 microns, the second stage includes a wound cartridge filter of 25 microns. The third stage includes finer filtration with activated carbon or carbon blocks.

The impurity ejection across stages involves both manual and automatic processes. In the first stage the impurities can be ejected manually using a drain tap and funnel. The anti-reflux system ensures that the discharged water does not come back into the system and prevents any washed-out dirt from re-entering the system. The filters are available with ½“, ¾“, 1” in/out connection in BSP or NPT brass and plastic thread.

FAQs

What are filter bags for?
Filter bags are an integral part of bag filter systems, used to capture and remove solid particles from liquids or gases. They help reduce downstream contamination and improve process efficiency across industries like chemicals, food & beverage, pharmaceuticals, and water treatment.
Gopani filter bags are available in materials such as polyester, polypropylene and nylon, plus specially treated media for high temperature or chemical resistance depending on your application.
Common collar options include steel ring collars, plastic collars and specialized welded collars to suit different housings and sealing methods.
Filtration ranges typically span from 1 micron to 500 microns depending on media and construction.
Flow rates depend on bag size, media and system design; we can help select the correct bag based on your LPM/GPM requirements.
Some filter bags can be cleaned and reused depending on the solids and application; however, single-use bags are common for contamination control.
Replace when you observe a significant pressure drop, physical damage to the bag, or when the recommended service life has been reached for your application.
