The Typhoon cyclonic pre-filter from CircuPool is the ultimate time-saver.

Using your existing pump and filter, the Typhoon turns your ordinary equipment into a sophisticated two-stage filtration system that delivers sparkling clear pool water and all but eliminates filter cleanings. With no moving parts to wear out and no electrical components, the Typhoon literally spins the dust and dirt out of your pool water using cyclone water flow.

Installation is an easy, ten minute do-it-yourself project for most homeowners. The Typhoon mounts on top of your pump so it fits right in to any equipment pad and, the 2 inch threaded couplings ensure free-flow operation on all pools.

Certified salt-pool safe: Compatible with all types of pumps and filters. CircuPool products are backed by USA-Based Expert Support & USA-Based Factory Warranty.

How It Works: Using similar vortex technology found in modern cyclonic home vacuum cleaners, the Typhoon removes most of the dirt from the water before it even reaches your filter. The TJ-16 has sixteen independent centrifugal chambers that spin-away impurities from the water, working most effectively on dense debris (debris that sinks). Its clear chamber lets you see how effective it is, and it can be cleaned in moments just by briefly opening its purge valve. Works great with any filter type; cartridge, sand, or Diatomacios Earth. The latest and greatest technology for pools- your pool store might not even know about it!

Have a D.E. Filter? Its recommended to utilize either 1) the optional bypass pipe, 2) the optional bypass plumbing kit, or 3) a do-it-yourself version of the bypass plumbing. Since the prefilter is so effective at removing sediment, these bypass options allow you to recharge your D.E. Filter with D.E. powder without the powder getting captured by the prefilter.

Q: If used with a de filter, would you need to add a bypass to add DE?

Asked by: Jim Jackson - 3/22/2020
A: Yes, that is a good way to plumb it so that it eliminates the chance of your DE powder getting captured by the prefilter.

Q: Will this effect the Water Flow Rate? because I have a chlorinator that needs a minimum WFR to work and its installed after this.

Asked by: Gary Cox - 11/11/2021
A: This allows a flow rate from 13-132 GPM, and if it has an impact on flow it seems pretty negligible (unlike your main filter).

Q: Also, we do not have nor want salt pool. I presume the cyclonic product works with both salt and regular forms of chlorination?

Asked by: Dennett - 5/6/2022
A: This works with virtually any swimming pool, but a "salt pool" is just a pool that uses a electronic chlorine generator which can sanitize the water at a fraction of the cost that traditional chlorine costs, provides much greater reliability, and provides higher water quality with less of a caustic "chlorine effect". There's a good reason why the majority of new pools use chlorine generators! You can see more about that here: Let us know what questions you might have! 866-766-5243

Q: I am running a test system with high algae content. I want to remove fines, but not necessarily all the algae. Can your cyclonic separator be run without the filter cartridge?

Asked by: Dave - 1/22/2020
A: Sure, this doesn't include a filter cartridge and if you don't want one then that would be a pretty common situation when used for aquaponics or something similiar.

Q: My problem is spruce evergreen needles . I cogs hair trap . Could or should the typhoon .be installed before the pump hair catcher ?

Asked by: paul donrovich - 12/21/2020
A: This goes after the pump and before the main filter. The pump's strainer basket is meant to capture the biggest debris.
