Follow the links below or scroll down to learn more.

Question:

Is there a lot of maintenance to do on a Biltwel vacuum truck?

Answer:

The truth is there is very little maintenance to do:

  • Grease 2 fan bearings once a week

  • Grease the drive line every 2 months

  • Change compressor oil every 400-600 hours or 4-6 months 

  • Tighten belts typically once a year

  • Change engine oil every 3,000 – 5,000 miles

  • Keep the unit clean

Question:

Why do you offer vacuum bodies with 2 compressor locations?

Answer:

Some customers require easy maintenance and others require maximum storage space, so Biltwel has bodies that satisfy the needs of both customers.

Question:

I have a truck mounted unit. Why am I constantly having U-Joint problems?

Answer:

Some manufactures use 1” cold roll steel drive lines Biltwel uses hollow core drive lines and heavy duty U-Joints installed at the same angle as the original truck drive shaft to provide maximum durability.

Question:

Whe body and dirt box of my truck-mounted unit rusts out very fast. Why?

Answer:

Other manufactures use cold rolled and hot rolled steel to fabricate their units. These types of steel rust very fast. Biltwel vacuum trucks are made with 12, 14 and 16 gauge galvanized steel, as well as stainless steel and aluminum. Our dirt boxes also have drainage holes to remove any moisture that may get into the dirt box.

Question:

Some manufactures have removed their suction inlet nozzle requiring the technician to climb into the hose storage compartment. Is this practical?

Answer:

Not in our opinion. Can you imagine having your technician climb into the hose bin and crawl across the dirt and dust covered hose bin floor. They are required to do this each time they hookup and unhook the vacuum hose up to 10 or 12 times a day.


Not to mention the fact that if the technician only requires 25ft. of vacuum hose he is forced to pull out all the vacuum hose, just to hookup to the suction inlet nozzle.

Another problem with this design is that the fan blades are exposed and are only a few inches away from the hose bin. A potential disaster is awaiting a technician who hooks-up a vacuum hose while the fan is in operation. There is a potential to sever a limb!

Another problem with this design is that when it comes to shutting off the vacuum unit and the bags go down or when shaking out the bags there is a plume of dust that bellows out of the suction intake nozzle covering the hose compartment and hoses in dust. Then the technician has to crawl across this dusty hose compartment floor when hooking up and unhooking the vacuum hose.

If you put a cap over the suction inlet nozzle it causes the dust to rise up above the bags covering the technician in dust while he is either shaking out the vacuum bags, or simply putting them away.

Biltwel’s suction inlet nozzle is safely and conveniently located 2” inside the vacuum body. The inlet nozzle has a safety screen to prevent large items from hitting the fan. The fan is also situated 46” away from the safety screen ensuring that a technician’s limb cannot come in contact with the fan.

Biltwel vacuum trucks have the suction inlet nozzle at the edge of the body this allows the plume of dust to rise to the atmosphere and not cover the compartments in dust.

Question:

Why is having a suction hookup on the side of the truck so important?

Answer:

Versatility. The Biltwel vacuum truck is available with either a single or double suction inlet nozzle.

A single nozzle will give the operator more storage space and a double nozzle will allow for easy hook ups on both sides of the Biltwel vacuum body. A double nozzle will allow you to run up to 150ft. of vacuum hose off the right side and 150ft. of vacuum hose off the left side at the same time. This is great when you want to clean 2 separate systems at the same time, which are located up to 300 ft. apart (i.e. town houses).

With a double nozzle up to 8 different suction hook up positions are possible without moving the truck (left, right, straight, an up on both sides).

The Biltwel vacuum truck gives the technician far more hookup options at the job site: drive in, back in, right side or left side. Other manufactures have to back in and are always working out of the back end of their unit. Backing in to a job site is not ideal especially when long or curved driveways, low hanging eaves., tree branches, or tight spaces are involved. With the Biltwel suction inlet nozzle being right at the edge of the body no hose is wasted. Other manufactures, that have their suction inlet nozzle on the back wall of their hose storage compartment, require an additional 10ft. of hose, just to get out of the hose compartment.

Question:

How important are suction/security doors?

Answer:

If you live in a large city or an area of high crime or if you live where rain and snow is an issue, suction and security doors allow you to put your vacuum and air line through doors in the body and then lock your main doors.


With a Biltwel vacuum truck the suction security door is located in the main door, 2” away from the suction inlet nozzle. This makes hooking up the hose quick and easy.We also offer an airline security port.


Other manufactures put the suction security door in the hose storage bin wall about 6ft. away from the suction inlet nozzle and require the technician to push the 10” vacuum hose through the door and then crawl to the suction inlet nozzle to hookup the remainder of the vacuum hose.

Question:

What are the 4 most important reasons to purchase a Biltwel vacuum truck?

Answer:

1. Power: Biltwel’s fast set up time, high-powered vacuum, and high pressure compressed air cleans ductwork and HVAC components faster than all portable types of equipment.

2. Storage Space: Being able to carry all your tools all the time makes your duct cleaning business cost efficient.

3. Image: When your technician pulls up to the front of your customer’s house or business with your Biltwel vacuum truck your customers know that you are a serious player in your marketplace. Our truck will give your customers confidence in your ability. When you start the Biltwel vacuum truck up and inflate the bags people passing by will stop and read your company name. It could be a few people on a quiet street to thousands on a busy avenue; you can not afford to pass up this type of advertising exposure. Portable equipment users do not have this luxury as electric portable equipment sits inside the house or building and gas portable equipment sits beside the house or building not observed from the street. Portable equipment vans just do not draw as much attention as compared with a Biltwel vacuum truck.

Frankly, the bigger the show you provide the more money people are willing to spend.

4. Resale Value: Biltwel vacuum trucks hold their value and are always in demand. People are always looking for used trucks even if it is 20 years old.

Question:

Why don’t other manufactures openly publish their fans CFM’s and Static Pressure, and air compressor CFM and PSI?

Answer:

We don’t know! To us it is a requirement. Let’s face it, you wouldn’t buy a car without knowing its horsepower, you wouldn’t buy a lawnmower without knowing its horsepower. As a responsible manufacture we provide you with published numbers on both our vacuum fan and air compressor’s performance. Many manufactures will quote you a manufactures bench test for their fans or a free air test, which is where they test their fan with no filter bags in place.

For air compressors, many manufactures will quote the horsepower of the motor powering the compressor not the compressor horsepower, which makes the compressor’s horsepower appear to be 5 times higher than it actually is. With a Biltwel vacuum truck we give you a field certified vacuum test by a fully independent testing agency, in accordance with ASHRAE, AABC guidelines on a final assembly vacuum truck with the filter bags in place. For our air compressors we give you the different CFM out puts for each compressor and we also give you the CFM out put that correspond with the various PSI outputs. Most purchasers of air compressors do not realize that the higher the compressors PSI output the lower its CFM output will be.
