Does Pullman-Holt's HEPA vacuums meet the EPA requirements for RRP?
Pullman-Holt meets or exceeds 100% of the EPA requirements for RRP. All Pullman-Holt HEPA Vacuums are equipped with HEPA filters that individually tested and certified at 99.97% efficiency at .3 microns.
|
Can a HEPA filter be washed or blown off with pressurized air to be cleaned?
No. If the HEPA filter gets wet, it is ruined and must be replaced. Blowing the filter re-introduces hazardous media that was previously captured into the environment, including the air people breathe. A clogged or used HEPA filter must be immediately replaced with a new HEPA filter.
|
How long will the HEPA filter last?
With proper maintenance and care of pre-filters and/or primary stages of filtration, HEPA filter will last a minimum of 12 to 18 months. If you have poor suction or air flow, there is a possibility that your HEPA filter has captured the maximum amount of particles and must be replaced. The first step is to replace the disposable paper filter collection bag to see if this improves performance. If replacing the paper filter bag does not improve suction, then try replacing the dacron pre-filter bag attached to the body of the HEPA filter. If a new dacron pre-filter bag does not improve suction, the HEPA filter has reached the maximum load factor and must be replaced.

Do Pullman vacuums meet the ASTM F1471 - 09 Std Test Meth for Air Cleaning Performance?
This regulation refers to complete air-moving systems, not just HEPA filters
|
Can I convert a standard "dry only" or “wet/dry vacuum” into a “HEPA vacuum” by just adding a HEPA filter?
No. The risk of unknowingly using a standard wet/dry vacuum to pick-up hazardous material would be very high. HEPA vacuums are configured at the factory with special pre-filtration and warning labels which are not included with standard wet/dry vacuums.

Vacuum experiencing poor suction?
There are many possible causes for a loss of suction. However, they are typically easily corrected:
The paper bag or pre-filter is full or clogged. There is an obstruction in the hose, or inlet scoop.
If vacuum has a dump valve, make sure it is closed.
A cracked, cut or leaky hose.
Check all filters. If dirty, this will cause poor airflow.
Make sure lid/cover is secured to the vacuum tank/canister. Check clamps, make sure they lock tightly. Make sure all gaskets on or around lid are good, check to see if they are cut, cracked, deformed or worn air-seal gaskets between motor head and tank.
Break, hole or leak in the vacuum tank.
If vacuum is heavily used or has been in service for a long period of time, the motor brushes may be worn down and need replaced. If motor brushes appear fine, then motor may need to replaced.
If none of the above is found and you are still experiencing a loss of suction, contact customer service (800-237-7582) for further direction.

How do I know what type and size of vacuum I need?
Depends on the application (see below):
For picking-up fine dry dust, especially from carpeted floors, try using an upright vacuum, canister vacuum or a backpack vacuum. These vacuums are very compact and portable, and usually include paper filter bags for easy handling and disposal. Some models are also equipped with above floor cleaning tools which make them effective for all around general cleaning.
For picking up floor stripping solutions, industrial liquids, and flood (high volume water recovery), we suggest wet/dry vacuums, front-mounted squeegee vacuums, and pump-out vacuums. Some models will include above floor cleaning tools.
For picking up wet or dry materials in a general industrial "shop" environment, use any of our wet/dry tank vacuums.
For picking up hazardous material, i.e. asbestos, lead, silica, mold, and biohazards, use a HEPA Vacuum that is equipped with an individually tested and certified HEPA filter. Some hazardous material pick-up requires the use of water or a surfactant to reduce the possibility of airborne dust, forexample asbestos abatement. For these type of applications, we suggest a a HEPA Vacuum that is equipped with a wet shut-off module.
|
How often do I need the change the pre-filter?
Check the pre-filters anytime there is a loss of suction. Changing pre-filters, including the disposable paper filter bag, will correct over 80% of performance problems. The increase air flow and productivity from changing pre-filters often will more than make-up for any additional cost. Some pre-filters like our dacron bag can be laundered and re-used when they become dirty or clogged.
|
How often do I need to change the filter?
This depends on the type of material being recovered, the number of hours in operation and adherence to suggested periodic maintenance procedures. To maximize the life of all pre-filters and HEPA filters, we suggest using disposable enclosed paper filter bags.
|
Can I purchase extra tools and hoses for my vacuum?
Yes, Pullman-Holt offers a broad range of vacuum attachments. Vacuum attachments, i.e. wands, hoses and pick-up tools (either 1.25” or 1.50” in diameter). Most commercial/industrial vacuums use 1.5” attachments. Domestic or household vacuums use 1.25” attachments. Many Pullman-Holt attachments are compatible with many other commercial/industrial vacuums.
|
Can I extend the length of my vacuum hose?
Most Pullman-Holt Vacuums are equipped with a 10-foot hose. It is possible to connect a series of hoses together to increase the working range of the vacuum. However, for all types of pick-up materials, wet suggest hoses that are not in excess of 30-feet in length, since this can result in a significant loss of airflow.
|
Can I get replacement parts or filters for my HEPA vacuum?
Yes, virtually all parts and components used in the manufacturing of all our vacuums are available for purchase. All filter components, for both current and discontinued models are stocked in our warehouse in Tampa, Florida. Please refer to our online parts schematics to identify and order the part you need.

What is the best HEPA vacuum for my needs?
For an economical, general purpose HEPA vacuum for light to medium pick-up of fine, dry particles, we suggest models 390ASB and 45HEPA. These models have been used extensively by professional and nonprofessional users. Excellent for schools, labs, health care facilities and anywhere a compact, portable HEPA vacuum is required. Noise suppressed motors make them ideal for use in public areas. Since 2010, the 390ASB and 45HEPA have been purchase to meet the requirements of the EPA RRP regulations.
For professional contractors, we suggest our models 102ASB, 86ASB and 30ASB models. These steel and steel/poly units are of extremely high quality and are designed to withstand the most abusive construction, restoration and abatement jobsites. The 86ASB and 102ASB can also be ordered with wet shut off modules which make them ideal for asbestos removal. These models have also been used for over 25 years by multiple agencies under the Federal Government including the U.S. Postal Service, U.S. Navy and U.S. Dept of Energy.

Vacuum does not turn on when on/off switch is activated.
Defective switch.
Problem with the power cord; check for continuity in cord.
Check for loose wire connection to switch.
Make sure there is power in outlet.
If using an extension cord, make sure it is the proper gauge.

Vacuum motor makes a loud noise:
As a motor ages with usage, the impeller fan blades in the motor may deteriorate causing breakage. When this happens there will be sounds emerging from the motor area. Turn the vacuum off to prevent any extensive damage to the motor. Some vacuum repair shops may carry replacement impeller blades but more often than not, the motor will have to be replaced.
Some vacuum motors rest inside the motor head assembly in a molded area secured by "tabs" that prevent the motor from moving. If one of the "tabs" breaks, then the motor will vibrate when running. This will cause a rattling sound. In this case, the motor is fine but motor housing parts, including new gaskets, will be required to secure the motor and prevent leaks.
|
There are sparks emitting from the motor head area:
When a vacuum is first put into service, the carbon brushes in the motor must seat themselves on the armature. This takes only a few seconds but it sometimes generate minimal sparking or smoke. If the sparking or smoke does not stop, turn the machine off. Check the website for a local service center or contact customer service to arrange an evaluation by an authorized Pullman-Holt technician. Note: IF the vacuum is a "dry only" vacuum and you have picked up liquid, this could also be the cause.

Can I buy original factory pre-filters and paper filter bags online?
Yes, you can click on "Filters and Bags, HEPA and Non HEPA" or "Buy Bags" in our online store. You can also search for the appropriate pre-filter or bag by clicking on your particular vacuum model.
