375hh Specifications, Features & Compatibility Guide
6 m³/min) at a maximum operating pressure of 14 bar.This 2014 kg unit utilizes a 91 kW (122 HP) diesel engine to drive an oil-injected rotary screw pump at 2100 rpm, ensuring high-volume air delivery for the most demanding construction jobsites.
Quick Answer
Yes, you should invest in the Sullair 375HH if your operations demand continuous, high-pressure air delivery for large-scale construction or industrial applications. Its 375 cfm at 14 bar and robust 91 kW diesel engine make it ideal for demanding tasks like pile driving or sandblasting, ensuring peak productivity on Indian job sites. It's built for reliability, not for residential use.
Opt for the Sullair 375HH if your high-pressure industrial or construction needs demand unwavering 375 cfm performance. This compressor is not for those seeking small-scale air solutions or prioritizing minimum capital expenditure over robust, continuous high-volume air supply.
✓ Who Should Buy
- • performance suitable for residential spaces.
- •Verified efficiency of standard rating for reduced long-term operational costs.
- •Structural stability for consistent cleaning under rigorous use cases.
- •Hardware durability via premium components and advanced technology.
- •Built-in grid protection with Standard power cycle voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding residential rated capacity.
- •Installations prioritizing minimum capital expenditure over high-efficiency performance.
- •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
- •Environments incompatible with compressors physical and thermal dissipation specs.
Product Overview
The Sullair 375HH is a purpose-built high-pressure solution delivering 375 cfm (10.6 m³/min) at a maximum operating pressure of 14 bar. This 2014 kg unit utilizes a 91 kW (122 HP) diesel engine to drive an oil-injected rotary screw pump at 2100 rpm, ensuring high-volume air delivery for the most demanding construction jobsites. Its 246 L fuel tank supports long-duration continuous duty cycles, while the direct-drive system eliminates the energy loss typical of belt-driven models. Designed for mobility, the 3967 mm long towable trailer features a powder-coated galvanneal sheet metal enclosure and a weather-proof instrument panel for extreme site conditions. Safety is prioritized via integrated low-oil shutdown, emergency stop, and overpressure protection, while AWF® all-weather fluid ensures the 10,600 LPM airflow remains stable across varied climates. Maintenance is simplified through a service indicator and a multi-piece canopy that provides direct access to the 91 kW motor and oil-injected pump internals.

Engineering Analysis
Engineering of the 375HH focuses on the 14 bar pressure threshold, which is significantly higher than standard 7 bar portable units, requiring the 91 kW motor to maintain a 2100 rpm output under high load. The use of an oil-injected rotary screw pump allows for continuous duty operation without the thermal degradation found in smaller reciprocating units. The 2014 kg mass is strategically distributed on a towable trailer with anti-vibration mounts to dampen the oscillations of the diesel-driven direct-drive system. Thermal protection and a pressure relief valve are specifically calibrated for the 14 bar peak, preventing system fatigue during 375 cfm maximum delivery. Moisture separation is integrated into the 10.6 m³/min air path to protect downstream high-pressure tools from condensate. The 246 L fuel tank is sized to match the consumption of the 91 kW engine at full 14 bar load, ensuring that the 10,600 LPM output does not require frequent refueling interruptions during critical industrial processes.
