Continental Contitech 20284272 Blower Duct Hose 1-1/2 in

Product Description

The CONTINENTAL CONTITECH 20284272 is a flexible PVC blower duct hose designed for low-pressure air-moving applications in HVAC, ventilation, and equipment service work. With a 1.5-inch inside diameter and a vacuum rating of 5 Hg, it handles moderate suction and airflow demands without collapsing under typical blower loads. The hose spans 100 feet and operates across a temperature range of 15 degrees F to 150 degrees F, making it suitable for both winter and warm-weather service conditions. The gray PVC construction offers flexibility and durability for routing through confined or irregular paths. HVAC technicians, equipment service crews, and industrial maintenance personnel are the primary installers.

This duct hose is rated for use with air conditioning equipment, leaf collection machines, and manhole blowers. Its 100-foot length provides enough run for most field installations without splicing. The 1.74-inch outside diameter keeps connections compact, and the 2.25-inch minimum bend radius allows routing around obstacles without kinking. It is well-suited to residential and light commercial ventilation setups as well as outdoor power equipment service applications where a flexible, temperature-tolerant air duct is required.

Key Features

• 1.5-inch inside diameter with 1.74-inch outside diameter for standard blower connections
• 100-foot length reduces the need for field splicing on longer runs
• 5 Hg vacuum rating handles typical blower and duct system suction loads
• Operating range of 15 degrees F to 150 degrees F suits year-round field use
• 2.25-inch minimum bend radius allows flexible routing in tight spaces
• PVC construction provides lightweight, corrosion-resistant performance

Compatibility

Rated for use with air conditioning equipment, leaf collection machines, and manhole blowers. Designed as a flexible duct hose solution for low-pressure air-moving systems requiring a 1.5-inch ID connection.

Installation Notes

Installation is typically performed by HVAC technicians or equipment service personnel. Power down or de-energize all connected blower or fan equipment before attaching or detaching duct hose. Secure hose ends with appropriate clamps to prevent air leaks and ensure the hose routing does not exceed the 2.25-inch minimum bend radius, as sharper bends can restrict airflow or cause kinking. Follow applicable local codes and equipment manufacturer guidelines for duct connection requirements.
