WestPak Professional Chemical Pre-Spray Systems (10-0507, 10-0518 & Pistol Grip)

from $150.00

Upgrade your commercial pre-treatment setup with industrial-grade WestPak chemical sprayers, engineered specifically for professional carpet cleaners, janitorial teams, and auto detailers. Built to withstand aggressive traffic lane cleaners, heavy-duty degreasers, and daily high-pressure use, these setups replace weak, unreliable pump-up sprayers with a consistent, commercial chemical application.

Choose between three heavy-duty configurations to match your preferred workflow and ergonomics:

• WestPak 10-0507 Flex Hose Sprayer ($150.00): Features a 45” flexible chemical-resistant hose, premium brass valve, 1/4” 6506 stainless steel nozzle tip, and an upright 5-quart jug. Rated as a 4:1 inline sprayer, it is perfect for maximum reach and maneuverability around tight commercial spaces.

• WestPak 10-0518 Straight Sprayer ($150.00): Equipped with a rigid 22” straight lance, premium brass valve, 1/4” 6506 nozzle tip, and an upright 5-quart jug. Also rated at a 4:1 ratio, this setup is ideal for precision, targeted application on heavy traffic lanes without the flex hose play.

• WestPak 10-0507-005 Pistol Grip Sprayer ($175.00): Features a heavy-duty, ergonomic pistol grip trigger gun assembly for maximum hand comfort and fatigue reduction during extended spray jobs. Includes a 45” flexible chemical-resistant hose, brass components, a 1/4” 6506 nozzle tip, and a 5-quart upright jug (4:1 ratio).

Both systems feature a suggested working pressure of 200 PSI and a maximum suggested liquid temperature rating under 180°F.

Important Shipping Note: To ensure you receive factory-fresh equipment, all WestPak chemical sprayers are drop-shipped directly from the manufacturer. Please allow up to 10 business days for delivery.

Best For:

  • Commercial carpet cleaning owner-operators tired of replacing cheap pump-up sprayers.

  • Auto detailing shops requiring a high-pressure, chemical-resistant upholstery pre-treatment gun.

  • Janitorial crews looking for an efficient, durable inline chemical application system.
