N270 SERIES OVERVIEW
N270 – DSTech’s Signature series
A heavy-duty pneumatic airless pump series designed for high-viscosity coatings and large-scale industrial projects. With a 10.6-inch air motor, advanced anti-freezing features, and a robust build, it delivers exceptional reliability and spray consistency even in extreme environments.
- Heavy-duty 10.6-inch air motor: High power for demanding industrial coatings
- Advanced anti-freezing system: Includes ice-breaking button, water drain system, and ventilation for reliable operation in cold or humid conditions
- Wide range of pressure ratios (47:1 to 95:1): Supports multiple applications and material types
- High delivery capacity: Up to 18.7 L/min for high productivity
- Durable stainless steel option: Superior corrosion resistance and long service life Versatile applications: construction, shipyards, protective coatings, metal structures
Features
Water that collects in the air motor can make the pump freezing.
However, convex piston plate and housing structure quickly drain water from inside the air motor. It keeps the air motor clean inside, and keeps it from freezing.
This allows manual re-start when pump freezes. Small particles like sand or grit disturb operation. Just push the button when the pump stops.
Cold air can freeze the air line, blocking air from coming out. The anti-freezing ventilation system of this new pump is designed to delay airline freezing.
This air regulator will work in extreme work conditions like sand blasting. Also, high input air volume reduces pulsation and gives more stable spray pressure.
This reduces noise.
