Howden Screw Compressor ((free)) | 2027 |

While service intervals are long, when something breaks, parts are expensive. A set of main bearings can cost $3,000–$5,000, and an OEM rotor replacement is nearly the cost of a new unit. Additionally, servicing requires specialized tooling and Howden-trained technicians—local general mechanics cannot handle it.

Oil change intervals are rated at 8,000+ hours (vs. 4,000–6,000 for budget brands). Bearing life is conservatively rated at 50,000 hours. After 12,000 hours, our unit showed no measurable rotor wear. The Bad (Cons) 1. High Initial Cost (Premium Tier) A Howden screw compressor typically costs 30-50% more than a comparable Chinese or Eastern European brand. You are paying for longevity and efficiency, but the capital expenditure (CAPEX) is a barrier for small operations. howden screw compressor

Unlike many competitors, Howden screw compressors handle dirty or corrosive gases well (with proper materials selection). We’ve compressed hydrocarbon mixtures with liquid carryover and minor particulates without rotor seizure. The robust bearings (SKF/FAG) are designed for thrust loads common in gas duty. While service intervals are long, when something breaks,

The cast-iron casing makes these compressors significantly heavier than rotary vane or scroll alternatives. For mobile or space-constrained installations (e.g., offshore platforms), this is a real issue. Oil change intervals are rated at 8,000+ hours (vs

First cost is your primary metric, or your application is light-duty (less than 4,000 hours/year).

The slide valve and stepless capacity control are smooth. From 100% down to 25% load, the compressor maintains stable discharge pressure without surging. The Vi (volume ratio) adjustment is also effective for varying suction pressures.
