Oblique Draft, Solid Back

The Accudraft 4000 prep or limited finishing station in oblique draft, solid back configuration delivers air in a front to back semi downdraft pattern. Air is delivered to the work space through the ceiling and air is exhausted out the rear of the workspace through a filtered back wall. Ideal for prep station installations where floorspace length is available and width is a concern. On a heated application, full heat recycle through a rear plenum gives you an efficient high-performance semi downdraft limited finishing station without sacrificing heat and energy efficiency. No concrete pits or excavation necessary.

Oblique Draft, Drive Through

The Accudraft 4000 prep or limited finishing station in oblique draft, drive-through configuration delivers air in a left to right or right to left semi downdraft pattern. Air is delivered to the work space through the ceiling and air is exhausted out the workspace through a filtered side wall. Floor plan and shop flow are optimized by allowing the car to be prepped and/or painted and then driven through to the next step. On a heated application, full heat recycle through a side plenum gives you an efficient high-performance semi downdraft limited finishing station without sacrificing heat and energy efficiency. No concrete pits or excavation necessary.

Downdraft

The Prep 4000 prep or limited finishing station in a downdraft configuration delivers air through the ceiling and air is exhausted through the floor underneath the vehicle and user. Available with heat and full heat recycle. Also available with a raised steel basement for a pit-less downdraft configuration giving you the best of both worlds: a true downdraft paint booth system and no concrete pit excavation necessary.

Accudraft-Prep-4000-Prep-Station-with-Backward-Inclined-Turbine-Exhaust-Fan

KD™ 500R Non-Loading Backward Inclined Turbine Exhaust System

The KD™ 500R non-loading exhaust system is built for high powered exhaust pressure capable of handling clogged filters and heavy loads of dust and debris that are common in vehicle pre and sanding areas. Specially engineered turbines create draft in some of the toughest conditions while keeping the turbine wheel from loading up with dust and overspray prolonging longevity an performance of the system between maintenance cycles.

Timeless Direct Drive

Also available in direct drive. Equal performance, less to maintain. User choice. Does not affect price. What’s the difference?

Prep Station Control Panel

The Accudraft 4000 prep station control panel lets the user turn on lights to work without having the airflow turned on if desired. The motor and turbine are turned on independently and recirculate 100% of the air being moved. This provides the worker great airflow in the workspace without emptying the shop’s conditioned air by exhausting it outdoors. When heat or air conditioning is present in the shop, this can save a lot by not impacting the shop’s utility costs. Only with the use of a manual or optional automatic switch will the prep station dump air to the outdoors.

SmartPad Prep Station Control Panel

If heat is added to a prep station or limited finish station, the Accudraft SmartPad paint booth control panel is included, allowing limited finishing with all the performance benefits of a heated paint booth complete with full heat recycling and flash, cure, and cool down modes.

Xcelerator

The Xcelerator was developed in order to help high production collision centers meet and surpass their financial goals. Often times, productivity is held back by paint drying time. Even the best managed collision center will eventually reach a production limit due to the finishing & drying process. The Accudraft Xcelerator can nearly double finishing speeds overnight, turning any new or existing spray booth into a high performance machine.

IRT Handheld Infrared Dryer

The IRT handheld dryer is a great addition to any finishing system. Dry spot jobs and hard-to-reach places in a snap.

IRT Hyperion Rail Mounted Short Wave Infrared Drying System

Reach just about anywhere on any job. High, low, side panel, top panel. It’s all the same to the IRT Hyperion rail system. Simply slide the adjustable arm anywhere you need it along the length of the booth or prep area and position the arm at the best angle to dry your job. The Hyperion will take it from there.

Optional KD™ Series Integrated Air Makeup System

Add the KD™ Series air makeup unit to your prep station for a fully heated and curing limited finishing station. The KD Series AMU is a completely integrated intake, heat, and exhaust system designed for high production paint booths. Forward curve and backward inclined turbines provide powerful airflow through the paint booth and recycled direct fire heating provides fast heating with maximum energy efficiency. Painters can put more jobs through the paint booth per hour and generate more profits for your business.

Do you need a prep station or a limited finishing station?

The answer is “it depends”.

First you have to ask yourself a few questions about the intended work that will take place in the work area.

What are you doing in the work area? Is it just automotive sanding and vehicle prep before bringing it into the paint booth? or do you intend to spray primer or paint in the work area also?

 

Automotive Prep and Sanding:

If the answer is that you strictly intend to sand and prep vehicles in a certain area of your collision repair facility, then you can install an automotive prep station. Operations that include vehicle sanding and prep only (no spraying paint or primer of any kind) allow you to use a simple prep station with exhaust and no further requirements. As a side-note if a prep station is what you need, make sure it is a recirculating prep station.

Prep stations may solve your problems of too much dust and debris, but may cost you thousands if the fan or fans are exhausting to the outdoors and have no option for recirculation.  In this case, conditioned shop air (either heated or air conditioned) is thrown outdoors and can add up to high utility bills. Make sure you see re-circulating on the products spec sheet or make sure you understand the way it works before you purchase it.

 

Limited Finishing:

If you intend to spray in the prep station work area, an exhaust-only automotive prep station will not suffice. As soon as any priming or paint spraying is going on, a limited finishing station is necessary by code.

A limited finishing station is a different tool than a prep station. Among others, a limited finishing station must include three main features that differentiate it from a typical automotive prep station.

1. A Full Roof (Closed Top or Ceiling) – This is for containment. Typically including light fixtures and filters, you will see the roof either free standing (supported by walls that make up the limited finishing station work space) or as ceiling or roof plenums hung from cables that attach to the shop ceiling.
2. Dedicated Intake Fan – A limited finishing station differs in regards to a an automotive prep station in that it must provide a dedicated intake fan. This is to ensure that the paint over-spray or contaminants are not drawn back into the limited finishing station’s work space.
3. Containment (Curtains or Walls) – A limited finishing station is required to have a partition on at least three sides of the work space. These partitions can be non-combustible curtains or walls.

Limitation of Spraying;

Although a limited finishing station meets code for spray application, it is not a paint booth. It is classified as “limited finishing station” which means no more than 1 gallon of material is to be sprayed in an 8 hour period. Spraying of more than 1 gallon of paint or coating material per day requires the installation of a fully enclosed paint booth.

 

Code Reference;

Below is the code referenced in determining the requirement of a limited finishing station over an automotive prep station.

You can also read up on many different practices recommended and required by the EPA regarding collision repair facilities at the EPA Collision Repair Campaign section of EPA.gov.

 

Recap:

Overall, the rule of thumb is that if you are going to be doing spraying of any kind, you should look into a limited finishing station instead of a prep-station. Please know that other restrictions and many codes regarding automotive prep stations, paint booths, and/or limited finishing stations may apply depending on building layout and requirements by local authorities. The best thing to do on any new project is to talk to an experienced finishing equipment professional in your area. They should be able to understand your needs and look at the intended equipment installation area and explain the applicable codes and permits associated with installing a paint booth, prep station, or limited finishing station.
