A cost-effective and efficient system available in multiple floor configurations.
The PARS2000 Pneumatic Abrasive Recovery System uses duct work and a vacuum system to efficiently collect and convey used abrasive media to a cyclonic separator, which separates reusable blast media from dust and foreign particulate matters.
It is an efficient and inexpensive solution for recovering used abrasive with minimal effort from the operator. It offers various floor hopper layouts. It can handle all major light-to-heavy abrasives available on the market except steel grit GH-36 or bigger and steel shot S-230.
This system is recommended for 8-hours-a-day blasting operations and is suitable for a large variety of applications. It provides a cost-effective alternative to the Mechanical Abrasive Recovery System when budget is limited.
The recovery rate capacity is 2,000 lb/hr.
The key advantages of a pneumatic abrasive recovery system:
After contact with work pieces, abrasive media falls on the floor and mixes with the blasting process by-products – paint chips, rust, scale, shattered blast media, solid debris, etc. In a pneumatic abrasive recovery system, the dirty media mix is sucked through a ducting vacuum system all the way to the cyclonic separator where particles are sorted out based on their specific density, through vortex separation.
The suction motion and power is generated from an impeller powered by an electric motor located on a dust collector next to the blast pot and cyclonic separator assembly. The dirty media mix is then drafted into the system from floor hoppers excavated in the floor or located above-ground.
Pneumatic abrasive recovery systems are very economical and efficient for most types of media. However, they have certain limitations in terms of floor layout and are not suitable for some applications. Here’s why.
Below each floor hopper, the dirty media mix is sucked through a 6-inch urethane vent duct to the cyclonic media separator. Since the suction power is determined by an impeller located on top of the reclaiming system’s dust collector, the length and possible configurations of the floor hoppers are limited by the suction power generated, resulting in lower floor coverage compared to mechanical recovery systems.
Common pneumatic system floor layouts may vary from a 4-foot corner shoot to a 40-foot long floor recovery pit, depending on the application and type of media.
This abrasive media recovery system is available with a choice of two abrasive media cleaning technologies, each designed to remove contaminants from the recovered media and return only clean, reusable abrasive media to the blast pot. Both systems help maximize blasting performance, maintain consistent process quality, and reduce abrasive media consumption.

This abrasive recovery system is delivered with a PARS2000 Cartridge Dust Collector which has an overall filter area of 200 sq. ft. and is equipped with a 10 hp / 800 cfm engine. Cartridge media can capture 99.9% of particles down to 1 µm, and an optional H.E.P.A. filter can be added to the exhaust to capture 99.98% of particulates down to 0.3 µm.
Its main function is to collect debris and foreign particulate matter sorted out by the cyclonic separator. It also generates the vacuum motion and power of the whole recovery system from an impeller powered by an electric engine mounted on its head for optimal efficiency.
This dust collector operates independently from the blast booth’s main dust collector, which is designed to draft away and collect airborne contaminants floating in the air during blasting operations.
The recovery system dust collector has a reinforced frame designed to resist a very high air suction demand. This dust collector is extremely sturdy and durable, and requires minimal supervision and maintenance from the operator. It is delivered with a standard vertical muffler, or an optional horizontal muffler when space is not available.
The storage hopper ranges from 3.5 to 100 cu. ft., depending on the available ceiling height space, and is used as a temporary storage unit for abrasive media while it exists in the cyclonic separator. When the pot runs empty, it must simply be depressurized to let the plunger fall, in order to refill it with media waiting in the storage hopper.

Kresco offers various types of recovery floors adapted according to your available production space and budget. In surface or excavated installations, dimensions can vary from 4 feet in length in compact facilities to over 40 feet for high-output industrial facilities. The configurations are practically infinite!
Shallow and space saving over-floor design, is easy to install and requires limited maintenance. 17” floor excavation is sufficient for existing floors. System can also be installed on concrete floor or on any other permanent or temporary floor.
We manufacture a complete line of Recovery Systems to accommodate sandblasting facilities constraints, and these systems are compatible with our equipment, other manufacturers’ equipment and even with self-made facilities. Good recovery systems respect the 3R fundamentals: Reduce, Reuse and Recycle the abrasive.
Here are the different floor recovery hoppers layouts available with this system.

Recycling abrasives results in substantial savings in abrasive consumption while protecting the environment from harmful sandblast dust. Because of its fragile molecular structure, non-recyclable media deteriorates quickly while generating harmful residual dust and substantially reducing operator visibility.
Although cost of steel-shot abrasive is about 10 times higher than non-recyclable media, steel shot can be recycled and used up to 100 times, compared to only once with non-recyclable media.
