Always use safe and common sense precautions when working with Air-Care equipment. Do not block walkways with equipment, and remove delicate and breakable articles from the immediate work area. The following are precautions that should be reviewed by all persons who will be involved in the cleaning activity.

• Other than the 3 filters, there are no user serviceable components in Air-Care TurboJets. Only trained technicians should attempt to make internal repairs on this equipment.

• Always unplug both power cords before removing the covers or working on the wiring.

• Inspect AC power plugs to be sure the ground pins are in place.

• Never connect power to Air-Care equipment unless all covers and safety shields are in place. Mechanical and electrical parts could activate and cause injury.

• Never allow anyone but a properly trained technician to use the equipment or cleaning products.

• All Air-Care equipment is designed for US standard 115 volt, 60 Hz AC. The Vent Vac III is optionally available in 220/240 Volt, 50/60 Hz Power. Always check the specifications on the equipment before connecting electrical power to Air-Care Equipment.


The Vent Vac III has significantly MORE static pressure than Air-Care TurboJet Negative Air Machines and will be able to pull heavy, moist or sandy construction debris out of dryer vents, commercial ducts, chimneys, and restoration areas. It is NOT meant to be a wet vacuum for liquids.

To test a Vent Vac III, plug one of the power cords into a suitable 120-volt outlet.

A) Line #1 will supply power to VAC1 and VAC2

B) Line #2 will provide power to VAC3 and VAC4.

If all 4 VAC Motors are to be used at one time, Line 1 and Line 2 must be plugged into 2 independent power outlets.

C) If you are not sure if 2 outlets are independent, press the center “test” button; the green power light will only light up if the 2 power cords are in independent power outlets. The optional 220/240 Volt Vent Vac III also requires 2 independent electrical outlets; each must be 7.5 to 10 amps. This version does not come with a “test” button and green power light. Also, the test light my not light in Canada, even with 2 independent outlets.


Because of a unique full flow check valve system, any combination of motors can be used. Any one motor can be used by itself or any 2 or 3 can be used with the same airflow and static pressure (water lift).

One motor will provide more airflow than most single motor shop or HEPA vacuums, and two motors will usually be more than adequate for most vacuuming needs. In those cases where extra power is required, simply plug in the 2nd power cord and turn on a 3rd or 4th motor as required.


The Vent Vac III is an extremely powerful and versatile tool. The 3” vacuum hose is ideal for collecting construction debris without clogging and can be directly inserted into a 4” air or dryer duct. It can also be used with the “Y” adapter paired up with an agitation tool, such as the Drill Powered Cable or optional Air Whisk to be inserted at the same location. When connecting to a dryer duct, it is important to clip the outside flap open for proper cleaning.

For collecting debris in a variety of situations, the 2 ¼” extension wand, crevice tool, floor tool, bulk pickup too and 4” round brush are very useful.

In a basement duct system, it is best to attach the 3” hose to the trunk line and drive the duct debris downward from the vents with an air tool or a power brush. The small particles that are most harmful to the lungs (under 10 Microns) will be carried in the airflow and captured by the Vent Vac filters. Larger debris may require additional agitation to be fully removed.

The Vent Vac III’s high volume and high static “water lift” make it even more effective at removing debris from smaller diameter air ducts than many other standard duct vacuums.

Air-Care has self-study and classroom and field training on how to clean all types of air systems, call 800-3229919 for details.


Prior to troubleshooting, check the following:

1. Be sure the power cords are plugged into 2 separate, dedicated power sources and verify that the wall outlet where the power cord is plugged into is working. (Plug in a lamp or other device and be sure it works properly).
2. Check that the dual stage, 20-gallon vacuum bag is not full, and that the 3rd stage electra gold pre-filter and 4th stage canister filters are not clogged.
3. Us the “test” button on the power panel to verify there are 2 independent power outlets being used.

PROBLEM 1: Low or no vacuum suction.
CHECK: 1. Filters are clogged, 2. Gasket is leaking, 3. One or more motors are not running, 4. The hose is clogged.
• Replace the dual stage, 20-gallon vacuum bag filter.

• Clean the 3rd stage gold filter.

• Clean or replace the 4th stage HEPA filter.

• Inspect the gaskets on the door and under the HEPA, then Call Air Care for repair parts.

• Run one motor at a time to determine which one is not running.

• Remove the hose and check for vacuum then reverse the hose to suck out clogged debris if vacuum is ok. If there is still no vacuum, call Air Care.


PROBLEM 2: Circuit breaker in building trips.
CHECK: Both power cords are plugged into the same circuit.

• Check test light on panel, if it does not light, only use 2 motors

• Find a second independent electrical circuit for the second power cord


PROBLEM 3 : Excessive noise.
CHECK: White check valve located in III cabinet is installed upside down (air flow arrow should point up), OR One or more motor is bad.

• Remove check valve and install in proper direction

• Turn on one motor at a time to determine which one is bad, and then call Air Care for a new motor.


The Vent Vac III requires a minimum amount of maintenance, normally limited to cleaning or replacing filters as they become filled with dirt and debris. It is always beneficial to keep the exterior and interior of the machine clean. A qualified technician should perform all electrical or mechanical repairs.

Filter Removal & Replacement

1. Turn off all the VAC motors, and unplug the Vent Vac III.

2. Open the front door and remove the bag from its 3” tube on the back side of the door.

3. Carefully remove the 2-stage bag filter and dispose of it properly in accordance with any local state or federal regulations applicable.

4. If there is noticeable debris build up on the 3rd stage gold filter below the bag filter, push it to the rear and lift it off and clean it. It can be rinsed with water or sprayed with Dynamite cleaner and rinsed, but it must be DRY before reinstalling it onto the HEPA canister filter.

5. To remove the 4th stage HEPA, release the top latch and both side latches and lift the vacuum tank off the base.

6. Lift the HEPA out and inspect it for damage or clogging.

7. Install a new HEPA filter, by placing it into the base with the “flow” arrow pointing down.

8. Install a new dual stage bag filter following the instructions on the bag. It collects heavy debris in the bottom section of the bag and lighter debris in the top section.
