Can I put the your products outside?

No, The HAL Extraction Booth is not designed to be used outdoors. We have partnered with another company, Agronomic Pods, who have retrofitted shipping containers with our technology for an outdoor solution.

Does your Booth come in another color?

You can have it in any color you want, as long as it’s white!

Is the HAL Extraction Booth temperature controlled?

No. The HAL Extraction Booth comes standard with a make-up air system. Make-up air can be supplied from a conditioned room in which the Booth is installed or from the outdoors. A temperature control system can be incorporated to the duct work of the Booth, we recommend coordinating with your HVAC engineer.


Can I run utilities, such as compressed air, electrical or a water lines, into the Booth?

Our Extraction Booths come with a Utility Penetration Plate, which contains 16 pre-punched penetrations. You will be able to run the necessary heating and cooling lines through these penetrations. The different dimensions are :  (2x) 3/4”, (4x) 1 1/8”, (8x) 1 3/8″, (2x) 1 3/4”. We also provide fire-rated hole seals for these penetrations when they are not being used.  Any electrical components installed in the Booth must be rated for a Class I / Division 1 space.


Are the lights interlocked with the ventilation?

Yes, per NFPA;

“All electrical components within the extraction room shall be interlocked with the hazardous exhaust system such that room lighting and other extraction room electrical equipment will only operate when the exhaust system is in operation.”

In accordance with this regulation the lights inside of the HAL Extraction Booth can only be turned in conjunction with the ventilation.

Does the Extraction Booth have a make-up air system?

Yes, HAL Extraction provides both a make-up air (supply) fan and a ventilation (exhaust) fan with each of our Booths.

Can I bring make up air from outside?

Yes. Make-up air can be supplied from the outside environment or from your building. Per NFPA 33 (2018) 7.5 “air exhausted from [areas] shall not be recirculated”. When bringing in air from the outside make sure you are not recycling the exhaust air

Where should the exhaust ducting be vented from / to in the HAL Extraction Booth.

Per NFPA 33 (2018) 7.4;

Air exhausted from [operations] shall be conducted by ducts directly to the outside of the building. Exhaust ducts shall follow the shortest route to the point of discharge.

The HAL Extraction Booth requires 12″ or 18″ ducting to comply with this regulation and successfully duct your unit to the outdoors.

Do air flow rates change automatically?

Yes. The HAL Extraction Booth has a sensor that communicates with the exhaust system’s controller to change the air flow rate accordingly. The Booth operates at the Base Air Flow Rate until atmospheric concentrations reach 10% or more of the Lower Explosive Limit (LEL) for your solvent.

Can I manually increase the air flow rate?

Yes. If your particular jurisdiction requires emergency evacuation controls, HAL Extraction can provide these components and programming at an additional cost.

What are the Air Changed per Hour (ACH)?

The Air Changes per Hour vary across out 13 different Extraction Booths.

The Model 85U (our smallest Extraction Booth) provides a minimum 43 Air Changes per Hour at the Base Air Flow Rate, and provides a minimum of 129 ACH at the Purge Air Flow Rate.

The Model 215U provides a minimum 17 ACH at the Base Air Flow Rate, and provides a minimum of 51 ACH at the Purge Air Flow Rate.

***The Critical Flow Series Booths provide double the ACH of the same sized Classic Series Booths***

What are the electrical requirements?

The HAL Extraction Booth (and all of its components) requires a 208VAC single-phase circuit for the Booth’s electrical systems. All other extraction equipment should draw power from a separate circuit.

Can I run the Booth off of 3-phase power?

No. The Booth is designed to run off a single-phase 208VAC circuit. In the event that your space only has 3-phase power available, a step-down transformer will need to be installed by a licensed electrician.

Do I need a stand-alone fire suppression system?

The HAL Extraction Booth does not come standard with an automatic fire suppression system. However, Per NFPA 1 (2018) an automatic fire suppression system is required inside of the Booth. “An automatic suppression system shall be provided within hoods, or enclosures, including duct work”

We offer as an additional package a standalone automatic fire suppression system. Included in the price for this package is the materials for the powder based system as well as coordination of installation and assembly.

As an alternative, and often cost effective approach, to purchasing a standalone fire suppression system the HAL Extraction Booth can be tied into a building-wide sprinkler system, by integrating sprinkler heads inside of the Booth, exhaust plenum, and exhaust duct.



Can I get documentation to submit to the city?

Yes, HAL Extraction provides the necessary documentation for the Booth’s approval process. For every unit, we provide a full set of annotated drawings,

Is your Booth fire rated?

A fire rating is not required for the walls so long as you comply with NFPA 33 (2018) 5.5;

“Booths shall be separated from other operations by a minimum distance of 915 mm (3 ft) or by a partition, wall, or floor/ceiling assembly having a minimum fire resistance rating of 1 hour”
