2PN and TD-S/TD-HS flexible hoses
Flexible hose and ducting from Hi-Tech Duravent are flame-retardant to UL94V-0 and are UL recognized products for safety-critical air handling applications. Hoses are available in 25-ft. lengths and can be cuffed for easy installation and tighter seals. The 2PN provides durability for positive- or negative-pressure movement of light particles or materials as well as for blower, exhaust, or smoke-removal systems. The TD-S/TD-HS, a one- or two-ply vinyl laminate polyester hose features a heavy-duty wearstrip that resists abrasion in temporary or mobile applications.
