Gardner Denver Belliss & Morcom have the ability to understand our customer’s specific requirements and are committed to ensuring we provide intelligent solutions that meet your ultimate needs.

Lowest Cost of Ownership

  • With the highest efficiency motors at 97.1% and the latest in extended life materials technology, both the VH & WH range continue to outperform all other 40 barg oil-free compressors in the PET industry. Maintenance costs are also kept to a minimum due to our unique shaftless motor, with no belts or bearings there are fewer parts to maintain, which can eliminate unscheduled downtime.

Low Power Consumption – High on Efficiency

  • With each compressor driven by our EEF compliant water cooled motor, our 3 stage oil-free compressor is proven to be the most power efficient design concept for a 40 barg PET compressor.

Small Compressor Footprint

  • Where space is at a premium, the Belliss & Morcom range of oil-free compressors offer a neatly arranged compressor system in the smallest footprint available. With no specialist foundations required, our compressor systems are easily installed and fully operational in the shortest possible time scale.

Balanced Operation

  • All Belliss & Morcom compressors are dynamically balanced, therefore removing the need for any special and expensive structural foundations. The compressor room floor is only required to carry the static weight of the compressor.

Maximum Oil-Free Air Quality

  • With absolutely no risk of contamination, Belliss & Morcom compression technology delivers the highest quality oil-free compressed air meaning no possibility of oil contamination in your process up to ISO 8573 class 0. The intrinsically oil-free air produced by a Belliss & Morcom compressor meets all air quality standards including Pure Air – ISO 8573-1.
