Enpac 431212 Dewatering Filter Bag 12 ft x 12 ft personal protective equipment

SKU CH-XPXJ-5N5G5

A 12 ft by 12 ft polypropylene dewatering filter bag with a 100 micron rating and 125.53 cu ft sediment capacity

  • Filters sediment to 100 micron for cleaner discharge
  • Handles up to 2,000 gpm flow rate for fast dewatering
  • Large 125.53 cu ft sediment volume reduces changeouts
  • Meets 40 CFR 122.26 NPDES standards for compliance
  • Durable polypropylene geo-textile construction withstands tough conditions

Enpac 431212 Dewatering Filter Bag

The Enpac 431212 is a dewatering filter bag built for sediment capture during pumping operations. It serves crews managing stormwater, construction runoff, or industrial discharge where sediment control is required. The bag connects to a 4 in discharge hose and handles flow rates up to 2,000 gpm. It meets 40 CFR 122.26 and NPDES standards for regulated discharge compliance.

Black Polypropylene Geo-Textile Construction

The bag uses black polypropylene geo-textile fabric rated at a 100 micron filtration level. It measures 144 in length by 12 ft width, providing 125.53 cu ft of sediment volume capacity and 4.4 lb weight capacity. The material is not incinerable and not approved for landfill disposal. It is designed for single use and contains no recycled content.

Replaces Improvised Sediment Containment

This bag replaces makeshift barriers or unrated fabric when regulated dewatering is needed. The jump is worth it when a project requires documented NPDES compliance and a defined micron rating. It is not suited for oil recovery tasks or applications needing reusable filtration. Buyers needing chemical absorption or multiple-cycle use should look elsewhere.

Questions about this item

What discharge hose size does the 4 in opening on the Enpac 431212 dewatering bag accept?

The bag is designed for use with a 4 in discharge hose and has a maximum discharge hose size of 4 in.

What are the dimensions and sediment volume capacity of the Enpac 431212 filter bag?

The bag measures 12 ft L x 12 ft W (144 in length) and provides a sediment capacity of 125.53 cu ft.

How is the Enpac 431212 dewatering bag installed on the hose, and what mistake should be avoided?

Slide the bag over the 4 in discharge hose and secure it tightly; the common error is failing to seal the connection, which allows unfiltered water to bypass the 100 micron polypropylene geo-textile.
