3500 Gallon/ 13250 Liter Fol-Da-Tank Portable Folding Frame Tank (MPN: FDT-3500/13250)

Description

The FOL-DA-TANK® 3500 Gallon / 13250 Liter Portable Folding Frame Tank is engineered for large-capacity water storage in rural firefighting operations where hydrants are unavailable. These collapsible tanks significantly increase water supply at fire scenes, making them essential for tanker shuttle operations, wildland firefighting, and emergency response.

Every folding frame tank comes standard with patented pinch-free hinge protectors that safeguard firefighters from hand and finger injuries during setup and folding. In addition, liner grab handles are integrated into the base, allowing for faster, safer folding and deployment. Fully NFPA 1142 compliant and GSA approved, this model meets strict performance standards for firefighting applications.

Constructed with HPR® (High Performance Rubber) liner fabric, this tank has been field-tested from Alaska’s sub-zero cold to the Middle East’s extreme heat. The material is designed with UV, puncture, and abrasion resistance, as well as flexibility down to -60°F. Backed by a Lifetime Seam Warranty, the HPR® liner ensures unmatched durability and reliability.
