Basket Filters are high-rate mechanical filters designed to extract organic debris and particulates from either rooftop or surface rainwater.
- simple, reliable underground pre-filter
- 100% recovery for roofs up to 5000 sq ft
- 4/6” inlet, 4/6” waste outlet, 4” filtered outlet
- cleanable, large-capacity filter basket
- 350 micron filtration
- heavy-duty, black, plastic telescopic riser
- heavy-duty, black, plastic pedestrian lid
- cast-iron lid for vehicle traffic
- slotted cast-iron grate for surface drainage
These basket filters are installed underground and include a telescopic accessway that is adjusted to match the pipe inverts. Rainwater enters through either of the top ports, flows down through a large screened filter basket, and flows out through the bottom port. The second top port serves as an overflow in the event the filter basket become full the water flow rate exceeds the capacity of the filter. For roofs up to 5,000 square feet. The maximum roof area per filter should be reduced 50% for seasonally dry climates intense rainfall. Basket filters are simple to install and can provide virtually 100% recovery efficiency. The filter basket is easily accessible, and except for periods of heavy leaf fall, rarely needs cleaning. Even when the bottom of the basket is covered with debris, the large sidewall surface area allow substantial flow. Optional, cast-iron lids are available.
Water from the roof enters through one of the top ports, flows through the basket, and exits at the bottom port. If the basket is clogged or the cistern cannot handle the hydraulic flow, unfiltered water overflows through the second top port. The filter has no direction, so either top port can be the inlet or overflow.
Contains 2 packages per filter with dimensional weights of 82 lbs. and 62 lbs. respectively. UPS also adds an extra $8.50 fee per system because of the size.
