Frequently Asked Questions

If someone has 110 volts available, even with a long extension cord the VM4BS500 is the way to go. Nothing beats the 500 watts of power that it offers with the exception of the 4.0 Peak HP VAC N BLO. Bottom line, I still push 110 volts over 12 volts. The 12 volt AM4BS comes in handy when 110-volt AC outlets are just not available (apartment/condo owners). As 12-volt cigarette lighter adaptor models go, this is the best. The vacs look identical with the exception of the motor and cord. VM is 110 volt and AM series is 12-volt. Both models also have the same MSRP.
Unfortunately, we have NO cordless vacs. They are not powerful enough and don’t have long enough run time. Maybe you can use a very long extension cord with any of the following products.
No, all of our vacuum cleaners are designed for DRY pick up only.
Every product we ship has a date code on it (usually on the bottom) indicating month and year it was built.
The cloth bag must be used in conjunction with the paper bag. You can continue to use the paper bag or just use the cotton cloth bag. Users don’t necessarily have to use the paper bags although it is a lot more sanitary to dispose of the paper bags than the “shake out the dirt” from the cloth bag. We also recommend that you continue using paper bags he 3 ply paper bags helps to prevent dust from entering the motor end environment.
To maximize the blowing power; remove the front end cap and cloth bag, leave the foam filter in place and leave it wide open. Do not replace the front end cap. The VAC N BLO is designed to blow water out
of hard to reach inaccessible areas of your vehicle. It is not capable of drying your entire car. You'd need the master blaster for that.
Unfortunately, we don't carry the adaptors. We suggest you bring the fan to a local RADIO SHACK. The cord that they supply should have a built in fuse, as well. They should be able to help you.
The Master Blaster features two twin fan 4.0 Peak Horse-power motors capable of delivering up to 58,000 feet-per-minute of clean, dry, warm, filtered air! Each motor is controlled by a separate switch that allows you to select from three different airflow and temperature levels up to 60º above ambient. If you use ONLY the FRONT motor, you’ll get one level of blowing power and heat. If you use ONLY the BACK motor, you’ll get another level of blowing power and heat. The truth is that these two scenarios above (of operating one motor at a time) are not really dramatically different.
You can use the front independently or the rear, it doesn’t make a difference.
The heat produced is directly related to the temperature that the unit is being used in. If it's a really hot day, it'll get real hot. If it's 65, you'll get maybe 115-125, or so.
Due to the tremendous velocity of air produced by our products, you may experience some air venting by the seams, this is completely normal and helps keep the unit running efficiently.

Occasionally, we will receive calls from users saying that their MASTER BLASTER & BLASTER HOSE is defective. 99.99% of the time it is not. We don’t glue one of the hose ends on the 10 or 30-foot hose to provide greater flexibility in adjusting the air flow. There are times that the hose end will come “unscrewed”.
The hose is not defective. The hose end came off.
You may have purchased a 120-volt product and are running at 220-240 volts. We do indeed manufacture 220-240 volt units that are suitable for use in your country. We don’t recommend the use of transformers.  You would need a new motor and new cord. By the time you get done with the cost of the components and shipping costs you may be better off ordering a NEW correct 220-240-volt product from one of our suppliers.
Please be sure you are not using spaces or dashes in between the cc numbers. If the problem continues, please call your bank to make sure they are not blocking the transaction.
The power control slide located on the hose end can be used to reduce suction or blowing power.
