Liberty Industries SHOE CLEANERS
A key initial product Liberty offered when first founded, Liberty Industries now offers a number of excellent shoe brush machines used prior to entering a cleanroom–something for any size contamination control area and number of employees. They’re listed below from an introductory model to the ultimate. (See www.liberty-ind.com for photos and additional data).
For a basic entry area where an effort is being made to reduce contamination, consider the 7345. Having an all-steel frame, it is well-designed with 1 1/2″ stiff, plastic bristles which are acid and weather resistant so it can be used inside and out.
The front, back, sides and soles of the shoes are cleaned via V-shaped, contoured brushes and a scraper designed to handle heavy accumulation. Just put one foot in in the unit while the other holds the unit securely, as the contamination drops down.
(Specifications: the cleaning surface is 100 square inches. The structural foam blocks are 3″ (w) x 10″ (l) x l 1/2″ (h), and are secured by steel swivel brackets which are bolted to an all steel frame.
FOR LIGHT DUTY CLEANROOMS, the Model 100-FJR
In anti-contamination areas that have a lower-to-mid volume of workers, the popular 100FJR is ideal, intended for lighter use in a dry environment. It comes with or without a top brush, in both 110V/60Hz, 220V/50Hz or 230V/60Hz. There are 2 vacuum systems available–the original Model 104 which is a 4-gallon, microstatic/bonderized version, or the current AS-5 HEPA vacuum. A solenoid valve and connecting kit, as well as replacement bags are available, as well as dozens of replacement parts.
FOR MODERATE DUTY CLEANROOMS: the Model 2001-TB shoe cleaning machine; CE-approved
If your cleanroom has notable traffic, or if the workers have either a metal toe, or a shoe larger than 3 1/2″ wide by 10″ long, the 2001-TB is the way to go. You just put your foot into the unit and its fully-automated features kick in! The unit has 4 motor-driven brushes on the top, bottom and sides. Liberty offers dozens of replacement parts to keep this unit in top condition for years. Specifications: 132 lbs.; unit 1/3 HP motor, 120V/60Hz gear motor; 20.25″ long x 19″ wide x 15.25″ high, and it has a 23.75″ support handle.
FOR HEAVY DUTY CLEANROOMS, the Model 2010-SC
A high-traffic cleanroom needs shoe cleaners able to hold up under serious use. Another motorized shoe brush machine Liberty manufacturers is the fully automatic, amazingly quiet and highly-efficient 2010-SC. This shoe brush machine features a 99.99%-effective HEPA filter exhaust system. The top-of-the-line unit is completely self-contained and the contaminate it removes can be easily cleaned out via its pull-out drawer. As with other units, a framed Liberty Tacky Mat® can be put in front to eliminate footborne dirt. Dimensions: 18″ wide x 28″ long x 39″ tall; 135 lbs.
THE BULL DOG (Model 351) for WET-DRY and industrial applications
When a cleanroom has people coming in via an area with high contamination (e.g. from an office area, a dirty warehouse, or even from OUTDOORS) the Bull Dog is the perfect selection. The 351 is a motorized shoe brush cleaner designed to handle all types of particulate, including snow or slush, yard “litter” (such as grass, leaves or dirt, mud or sand). Specifications are: 16″ wide x 21″ long x 44″ tall; 135 lbs, 120V/60Hz.
