Intewa's patented self-cleaning Purain Rainwater PR100 filter for rainwater or grey water filtering applications in single-family dwellings for discharge pipes up to DN100 (standard 110mm dia waste pipe). The filter uses the hydraulic jump principle to generate the self-cleaning vortex during high-intensity rainfall events.
This filter is able to accommodate the flow from several downpipes by bringing them together into a single 110mm pipe. It is suitable for installation within a tank, above a tank or in an underground chamber. Suitable for roof areas up to 200sqm or 5.1l/s flow rate.
Features:
- stainless steel trapezoidal gap sieve (aperture 1mm)
- integral skimmer overflow to remove any floating debris
- minimal height offset
- minimal maintenance intervals
- self-cleaning due to the hydraulic jump effect
- minimal blocking due to the trapezoidal gap sieve design
-minimal blocking due to distribution over the total sieve surface
-immediate filtering performance with no start-up losses
-minimal tilt sensitivity
-integrated non-return valve (NRV) to prevent backflow and/or small animals from entering the tank.
- a backflushing nozzle can be installed as a separate item to periodically flush the screen clean (from behind) with a jet of water (for grey water applications or other heavy solids loading applications)
- a 110mm spigot with a seal in the inlet to receive a 110mm dia PVC waste pipe.
- a 110mm outlet which can be connected to a 110mm outlet pipe using a standard 110mm straight coupling available from any plumbing or hardware store.
