Inlet Guard for Storm Drains

The Ultratech 9162 inlet guard fits storm drain openings to capture debris, oil and sediment before they enter the drainage system. It is intended for facilities and worksites that must manage surface runoff at the point of entry.

Practical Limits of the Guard

The guard handles a flow capacity of 192 gpm through a 4-1/2 in diameter opening and measures 24 in by 36 in. It is not rated for oil capacity, so it suits sediment and debris control rather than dedicated hydrocarbon containment.

Non-Woven Polypropylene Material

The single specification that decides fit is the non-woven polypropylene construction, which determines chemical resistance and service life in wet, outdoor conditions. Buyers who need a different media or a rated oil capacity should select an alternative product.

Questions about this item

Should I choose the 24 in by 36 in size for my storm drain inlet?

The guard measures 24 in long by 36 in wide and fits a 4-1/2 in diameter opening, so match those dimensions to your inlet before ordering.

What does the 192 gpm flow capacity mean when the guard is installed?

It allows up to 192 gallons per minute of water to pass while trapping debris, oil and sediment, so drainage keeps pace with heavy runoff.

How does the non-woven polypropylene material affect what the guard can capture?

The polypropylene fabric stops debris, oil and sediment from entering the storm drain while letting water flow through at the rated 192 gpm.
