Flexaust 3504030000 Vacuum Duct Hose 3 Inch Id 25 Ft Pvc

Product Description

The FLEXAUST 3504030000 is a polyvinylchloride (PVC) vacuum duct hose designed for air, dust, and fume evacuation in industrial and commercial ventilation applications. With a 3-inch inside diameter and 25-foot length, it handles a vacuum rating of 22 Hg and a maximum working pressure of 18 psi. The crush-resistant construction maintains airflow under compression loads common in portable vacuum systems and duct runs. Wall thickness measures 0.03 inches. The hose operates across a temperature range of 20 degrees F to 160 degrees F, making it suitable for year-round use in unheated spaces and moderate-heat environments. Installation is handled by HVAC technicians, duct installers, and industrial maintenance trades.

This hose is used in residential and commercial ventilation setups where flexible duct runs are required to move air, dust, or fumes from a source to a collection or exhaust point. Typical applications include portable industrial vacuums, dust collection systems, fume extraction, and general-purpose air handling. The 25-foot length provides adequate reach for most single-zone runs without splicing. The black PVC construction resists kinking and retains its circular cross-section under normal bending loads, with a bend radius of 3.7 inches.

Key Features

• 3-inch inside diameter for high-volume airflow in dust and fume applications
• 22 Hg vacuum rating supports strong suction without hose collapse
• 18 psi maximum working pressure rated for pressurized duct use
• Crush-resistant PVC construction maintains shape under compression
• Wide temperature range: 20 degrees F to 160 degrees F
• 25-foot length reduces the need for couplings in standard runs

Compatibility

Designed as an OEM-style flexible duct hose replacement for air, dust, and fume handling systems requiring a 3-inch ID vacuum-rated hose.

Installation Notes

Install this hose using standard hose clamps or barbed fittings sized for a 3-inch ID connection. Ensure all upstream equipment — vacuums, blowers, or fans — is powered down before connecting or disconnecting the hose. Avoid sharp bend angles tighter than the 3.7-inch minimum bend radius to prevent flow restriction or hose fatigue. HVAC and ventilation installers should verify that system vacuum and pressure ratings do not exceed the hose specifications before placing the system in service.
