Frequently Asked Questions - Air Force Master Blaster MB-3CDSWB220 MetroVac

How do I clean the filter on the MetroVac Air Force Master Blaster?
The filter is a washable foam pre-filter. Simply remove it from the intake, rinse with mild soap and water, allow to air dry completely, then reinstall. Do not operate without the filter.
Can I use this vacuum as a blower only?
Yes, the Master Blaster is primarily a blower/dryer. It is designed to blow air at high velocity for drying cars, floors, or equipment. It is not a conventional vacuum for suction.
What are the two speed settings used for?
Low speed is for general drying or lighter tasks, while high speed provides maximum air velocity for heavy drying or removing stubborn moisture. Use low speed to save energy and reduce noise.
How do I store the power cord?
The unit has dual cord wrap hooks on the rear. Simply wrap the cord around these hooks for tidy storage. Ensure the cord is not kinked or damaged.
What safety precautions should I follow?
Always operate on a dry surface, avoid water ingress into the motor, use a GFCI outlet, keep away from debris, and unplug when not in use. Do not block air intake or exhaust.
Can I use attachments from other brands?
Standard 1.25-inch or 1.5-inch attachments may fit, but we recommend using genuine MetroVac accessories for optimal performance and safety.
How loud is the Master Blaster?
Noise level is approximately 95 dB on high speed. Use ear protection when operating for extended periods.
What is the warranty period?
MetroVac offers a 5-year limited warranty against defects in materials and workmanship. Register your product online for coverage.
Can I use it to dry my pet?
Yes, but use low speed and keep the nozzle at a safe distance to avoid startling or injuring the animal. Ensure the pet is comfortable with air flow.
How do I change the motor brushes?
The motor brushes are accessible via screw-on caps on the sides of the motor housing. Use a screwdriver to remove caps, replace brushes with genuine parts, and secure caps. Consult manual for details.
