Drain Gun for Condensate Lines, Swoosh Big Shot

DiversiTech SG-1 – SWOOSH® Big Shot™ CO₂ Drain Line Cleaning Tool

The DiversiTech SG-1 SWOOSH® Big Shot™ is a high-pressure CO₂-powered tool engineered for clearing HVAC condensate and other drain lines without chemicals or water. Designed to deliver up to 800 PSI of oil-free air, this drain cleaning tool uses replaceable 20-gram CO₂ cartridges to quickly and safely dislodge debris and restore flow in 3/8" to 3/4" drain openings.

Key Features

• High-Pressure Discharge: Generates 800 PSI of dry CO₂ pressure to force clogs out of small-diameter drain lines
• Expanded Capacity: Accepts 20g cartridges for extended operation (25% more than 16g versions)
• Versatile Fit: Compatible with most 3/8" to 3/4" drain lines including HVAC condensate drains
• Flexible Hose Assembly: Enables precise access in tight or obstructed areas such as wall cavities and mechanical cabinets
• Tool-Free Cartridge Replacement: Designed for rapid cartridge exchange during field service work

Applications

Ideal for HVAC technicians performing regular maintenance or emergency service on mini-split systems, RTUs, and residential or light commercial condensate drainage. The SG-1 is suitable for use on PVC, CPVC, or polyethylene drain lines where mechanical agitation or water pressure is not feasible.

Technical Specifications

• Operating Pressure: Up to 800 PSI (CO₂)
• Cartridge Type: 20-gram CO₂ (threaded)
• Drain Size Compatibility: 3/8" – 3/4" OD
