New Tier 3 oil-free compressor from Sullair

Sullair has launched a Tier 3 engine-powered version of its OFD1550 oil-free portable air compressor.

The compressor is for applications including construction, plants or refineries, and provides 1,550 cfm of air with adjustable pressures up to 150 psi. The launch adds to the Tier 4 Final version, which was introduced in early 2019.

The Tier 3 model, which will be suitable for markets where emission regulations are less stringent, is available with either Caterpillar or Perkins engines. The unit includes a two-stage Sullair air end with high-efficiency rotors designed for oil-free operation. The rotors are coated with an FDA-approved food-grade PTFE to help resist corrosion and extend air end life.

“Since we introduced our Tier 4 Final OFD1550, we’ve seen a tremendous response from our rental customers and end users, so we’re pleased to introduce the Tier 3-compliant unit into additional markets,” said Jerel Cole, senior product manager at Sullair.

“The oil-free market continues to expand, and this compressor will help satisfy increased customer demand.

The Tier 3 OFD1550 has features implemented following customer feedback, including a touch screen controller providing compressor and engine operation data; the ability to operate at altitudes of up to 12,000 ft (3,658 m) above sea level; ease of serviceability and large access doors for easy cooler cleaning, and Sullair AirLinx remote monitoring and telematics.

It also features complete fluid containment to meet standards in environmentally sensitive areas. Optional extras include a Refinery Package (including anti-static belt, non-metallic fan, and spark arrestor) and a Cold Weather Package allowing operation at temperatures as low as -20°F (-29°C).

Sullair is a subsidiary of Hitachi Group, with U.S. manufacturing plants in Michigan City and Indiana, and in China (Suzhou), along with a IHI-Sullair joint venture in Suzhou.
