Affordable stormwater quality improvement systems. Ideal for catch basins. Converts any sumped stormwater structure into an oil-water-debris separator. Reduces floatables, free oil, grit and suspended solids. Attaches to catch basin wall over any type pipe. Models for rectangular and round structures, sizes from 12" to 96" are available. A removable water-tight clean-out port is standard for easy access to pipe. Anti-siphon device prevents contaminants frombeing drawn downstream. High flow, low headloss design. Strong, light-weight plastic composite construction is very durable and installs quickly. Unaffected by corrosive ice melting chemicals.

NOTES

1. All hoods are constructed of a glass-reinforced resin compound with ISO gel coat exterior finish with a minimum laminate thickness of 1/8 inch
2. All hoods are equipped with a water-tight access port, a mounting flange, and an anti-siphon vent
3. The size and position of the hood is determined by the outlet pipe size
4. The bottom of the hood should extend downward a distance equal to half the outlet pipe diameter with a minimum distance of 6" for pipes less than 12" I.D.
5. The anti-siphon vent should extend above the hood by a minimum of 3" and a maximum of 24" according to the structure configuration
6. The surface of the structure where the hood is mounted must be finished smooth and free of loose material
7. The hood shall be securely attached to the structure wall with 3/8" stainless steel bolts and an oil-resistant gasket
8. An installation kit is furnished which includes
   1. Installation instructions
   2. PVC anti-siphon vent pipe and adapter
   3. Oil-resistant crushed cell foam gasket with PSA backing
   4. 3/8" Stainless steel bolts
   5. Anchor shields

OPTIONS

1. Flow Restrictor Controls discharge rate Use for flood control Provides quality and quantity control Replaces orifice plate for ‘clog-free’ outlet control 2. Flow Diffuser Reduces fluid stream energy Promotes precipitation of suspended solids Improves separation efficiency with a smaller footprint Easily installed in any shape inline structure Stainless steel construction for long life 3. Sand Filter Improves sand filter performance Decreases organics and litter loading to sand bed Increases service life of filter media For new or existing sand filter High quality composite construction 4. Odor Control Filter Attaches to the end of the anti-siphon pipe Has a disposable carbon filter cartridge which screens out odors from outfall pipe Requires periodic inspection/replacement
