Nash MHF / AHF Series Replacements

Airvac Series – Single Stage, Port Plate, Liquid Ring Vacuum Pumps

Our high efficiency close-coupled liquid ring AVHF Series vacuum pumps are an excellent choice, producing up to 40% more capacity per horsepower. These new premium 50-120 CFM vacuum pumps are coupled to high efficiency 3-7.5 HP IEC frame motors and have been designed from the ground-up to be interchangeable with Nash classic AHF and MHF series pumps. AVHF series vacuum pumps are factory tested and include a 1-year warranty.

We have directly interchangeable parts with the NASH Classic AHF/MHF.

The 50-120 CFM close coupled liquid ring pumps are designed as drop-in replacements for both the Nash AHF and MHF classic series models. These robust vacuum pumps boast high CFM – HP ratios and are suited to applications such as poultry evisceration and vacuum thermoforming.
