Suction Blast Cabinets

Pro-Finish™ suction cabinets cost less and are simpler than pressure cabinets. They also blast continuously without the need to stop for media refills, and they simplify the use of multiple nozzles. The results are usually comparable to those achieved with a pressure system although production rates are not so high. When initial cost and maintenance are primary concerns, the suction system is a good choice.

Pro-Finish suction systems come in five sizes and can be specified with a collector or dust bag on smaller units. A media reclaimer is optional. Nevertheless, when using media that can be recovered, a reclaimer is advisable because it normally pays for itself quickly in terms of reduced waste and high-quality, repeatable results.

Pro-Finish suction cabinets are available with many factory options that contribute ease of operation, reduced maintenance and greater productivity. Plus, Pro-Finish’s modular design lets you upgrade to a pressure system in the field at any time, enabling you to build on your original investment.

Pressure Blast Cabinets

Because pressure cabinets deliver blast media at higher velocities than suction systems, a Pro-Finish™ pressure cabinet is ideal for turning out work fast. In many applications, these pressure cabinets will perform jobs four-times faster than suction systems. In addition, they use compressed air more efficiently and provide more precise blasting control at high and low operating pressures. For really demanding tasks, like removing tight mill scale or finishing hard-to-reach surfaces, a pressure system is normally the only practical choice.

Pro-Finish™ pressure cabinets come in six sizes with dust collectors and media reclaimers provided as standard equipment. (Less expensive dust bags can be specified with some models.)

With Empire reclaimers, Pro-Finish pressure cabinets not only reduce operating cost associated with the purchase and disposal of media, but also assure consistent results shift after shift. Plus, they are available with options designed to meet almost any
production need.

Ergo-Blast™ Cabinets

Empire® offers a number of standard Pro-Finish™ variations for specialized air-blasting jobs. Ergo-Blast systems, for instance, increase productivity by improving operator performance during extended periods of continuous blasting. These cabinets are ergonomically designed for sit-down operation and include other features to reduce fatigue. As a result, machine operators concentrate on the job at hand when working for hours of repetitive tasks rather than trying to find the best position to relieve a sore back. By removing every-day distractions, Ergo-Blast cabinets maximize production.

FaStrip™ Cabinets

Empire® offers a number of standard Pro-Finish™ variations for specialized air-blasting Pro-finish™ FaStrip™ cabinets are specifically designed for use with low -density media, such as plastics, that provide fast coverage without eroding substrates. Paint stripping, for example, can be performed quickly and economically without the use of hazardous chemicals. FaStrip cabinets deliver plastic or organic media from a large venturi nozzle coupled to a grounded, flexible blast hose. A large, vibrating screen within the reclaimer and Empire’s exclusive automatic Sure-Flo media regulator, working in tandem with the MG-78 CR exhaust valve, keeps light media flowing smoothly. A magnetic separator is also included in the system to extract ferrous particles that can damage delicate substrates.

Rotary Head for Blasting Complex Geometries

In many applications, parts that require cleaning will have complex geometries in the design of the part. This becomes a challenge to achieve a clean part due to many angles and areas that can trap contaminants.

An example of a common application with complex geometries is cleaning airfoils. These airfoils are typically 3-4 vanes made into a single fabricated piece. The pitch of the blades and the proximity to each other makes it difficult to access all of the different faces.

The main blast cleaning technologies that are used in this application include linear oscillators and swing arm oscillators. In a linear oscillator, the part gets hit only one time. With swing arm oscillators the arm travels in an arc and goes left and right, still only getting one pass and hit at one angle.

However, by using a rotary head you get two passes; one on the leading edge and one on the trailing edge. This doubles the exposure time and the number of angles, plus the rotary head is rotating so you achieve complete 360 degree coverage.
