GCTek MultiCyclone 50 Prefilter
The GCTek MultiCyclone 50 Prefilter is a solids separator that works better the faster you push water through it. Most prefilters separate best at slow flow, but in the MultiCyclone higher flow strengthens the cyclone, so centrifugal force throws solids out of the water. It catches up to 80% of the solids before they reach your filter, and a purge takes only 3 to 4 gallons of water.
• Flow Range: Minimum 13 GPM up to a maximum of 132 GPM.
• Up to 80% of Solids: Removed before they reach the filter, so the filter works more efficiently.
• Low-Water Purge: About 3 to 4 gallons per purge.
• Compact: Measures 24″ × 11.5″.
• After the Pump: Install it after the pump, before the filter.

How the MultiCyclone Solids Separator Works
- Cyclone design uses centrifugal force to separate solids from water
- Higher flow makes the cyclone work better, not worse
- Solids collect for a quick 3 to 4 gallon purge
- Up to 80% fewer solids reach your filter
Before You Order a Cyclone Pond Pre-Filter
- Plumb the MC50 after the pump. GC Tek recommends a strainer-type prefilter before the pump as well.
- Make sure your pump flow falls between 13 and 132 GPM.
- The MC50 can also be added to a GCTek WattMizer PLUS PRO system. Ask us.
