The MetroVac Air Force Master Blaster MB-3 is a two-speed pet dryer with two 4.0 peak HP motors. It uses forced airflow without a heating element and is built with an all-steel body for a grooming workspace. The MB-3 designation identifies the two-speed model within a range that also includes a variable-speed version.

A 10-foot commercial hose provides reach around the grooming area. The supplied attachments include a large blower nozzle, crevice tool, air flare and adaptor, allowing the outlet to be arranged for different drying tasks.

The unit weighs 17 lb, and the published 120 V specification lists an 18 A electrical load. Match the power supply to the equipment requirements when setting up the dryer.
