Flexaust 3641020000 Polyurethane Duct Hose 2 in Id 25 Ft

Product Description

The FLEXAUST 3641020000 is a polyurethane duct hose designed for demanding industrial and commercial ventilation, dust collection, fume extraction, and material handling applications. Constructed with a polyurethane wall, this hose delivers a 29 Hg vacuum rating and a maximum working pressure of 50 psi, making it suitable for both positive-pressure and vacuum-side installations. The hose measures 2 inches inside diameter and ships in a 25-foot length. A wall thickness of 0.04 inches contributes to flexibility while maintaining structural integrity across its rated temperature range of -65 to 200 degrees F. It is typically installed by HVAC technicians, industrial ventilation contractors, and facilities maintenance professionals.

This duct hose is suited for use in dust collection systems, fume exhaust lines, and bulk material conveying setups in residential, commercial, and light industrial environments. Its black polyurethane construction handles applications involving dust, fumes, and granular materials. The 2.5-inch bend radius allows routing through tight mechanical spaces without kinking, and the temperature range supports both cold-environment and moderate-heat applications. The 25-foot continuous length reduces the number of couplings required in longer runs.

Key Features

• Polyurethane construction resists abrasion and supports flexible routing in dust and fume extraction systems
• 29 Hg vacuum rating suitable for vacuum-side duct connections
• 50 psi maximum working pressure for positive-pressure installations
• Operating temperature range of -65 to 200 degrees F for cold and warm service environments
• 2.5-inch minimum bend radius allows installation in confined spaces without kinking
• 0.04-inch wall thickness balances flexibility with durability
• 25-foot continuous length minimizes field joints in longer duct runs

Compatibility

Designed for use in dust, fume, and material handling duct systems requiring a 2-inch inside diameter flexible hose with vacuum and pressure capability. Consult system design specifications to confirm pressure, temperature, and chemical compatibility before installation.

Installation Notes

Installation is typically performed by HVAC technicians or industrial ventilation contractors following applicable mechanical and ventilation codes. Before connecting or disconnecting the hose, shut down the associated blower, fan, or vacuum system and de-energize any electrically driven equipment in the line. Secure both ends with appropriate hose clamps or couplings rated for the system pressure and vacuum levels. Avoid routing the hose over sharp edges or through areas where the minimum bend radius of 2.5 inches cannot be maintained.
