Storm Drain Filter Inserts

Storm Adjustable Frame Model Drain Filter

Traditional storm drain filters often depend on the heavy storm drain grate for support, which can lead to complications during maintenance. When the grate is lifted for servicing, the filter tends to fall to the bottom of the catch basin, causing unnecessary delays and frustration.

With our Adjustable Storm Drain Filter, specifically the Adjustable Ultra Drain Guard, you can avoid this hassle entirely. This innovative filter is supported by a durable steel framework, ensuring it remains securely in place even when the grate is removed.

Adjustable Storm Drain Guard Details

There are various conventional storm drain guards, most of which rely on being placed directly in the catch basin. This often requires trimming excess fabric to fit the storm drain opening, which can be cumbersome, especially when the drain fills up.

The Adjustable Frame Model, however, offers a different approach. Instead of relying on conventional methods, this model features a sturdy steel framework that adjusts to fit different drain sizes seamlessly.

What are the advantages of this installation method? For one, the Adjustable Frame Model stays securely in place even when the storm drain grate is lifted. Unlike traditional models, there’s no need to secure the guard beforehand, eliminating the risk of it falling into the basin during maintenance.

Another benefit is aesthetics; there’s no excess material that needs trimming or could protrude above the grate. This results in a clean and streamlined installation, enhancing the overall appearance of the drainage system.

Stormwater Filter Guard Applications

The Adjustable Frame Model Drain Guard adjusts to fit different drain sizes without the need for trimming excess fabric. It catches silt, sediment, and debris as it enters a storm drain. Perfect for construction sites wanting to protect storm drains from stormwater runoff, the Adjustable Frame Model and Economy Frame Model Storm Drain Guard make installation simple and easy. You can't afford to waste precious time on the jobsite. Now you don't have to. When it's time to remove the Adjustable Frame Storm Drain Guard, the drain guard itself is held in place by the frame, so you can easily remove it.

Adjustable Frame Model Storm Drain FAQs

The Adjustable Frame Drain Guard can be reused. Typically, each Ultra Drain Guard can be reused, as long as the silt, sediment, and debris are removed from it. If oil and hydrocarbons have been filtered, then the drain guard needs to be disposed of properly in accordance with local regulations. The frame of this drain guard can also be reused, and you can purchase a 10-pack of filters (Part# 8932). To place a new filter on an existing frame, simply remove the old fabric by pulling apart the hook and loop fasteners around the top perimeter of the drain guard and replace it with the new one. The Economy Frame Model cannot be reused.

The life span of a typical drain guard varies depending on the location and environmental conditions. High volumes of stormwater and pollutants will have an effect on the filter's life expectancy. It is recommended that you check the drain guard after each rainfall event to inspect its effectiveness.
