Using normal parameters of nozzle pressure a Pauli pressure blast machine will outstrip a suction machine many times over. ![RAM31 SP Shot Blast](https://www.paulisystems.com/hs-fs/file-17539817-jpg/images/ram31-sp_shot_blast.jpg?width=394&height=264&name=ram31-sp_shot_blast.jpg)   ####  [Download RAM31-SP Brochure](https://www.paulisystems.com/hs-fs/file-17544467-pdf/docs/ram31-sp_shot_blast_system.pdf?hsLang=en-us) ![pdf icon](https://www.paulisystems.com/hs-fs/file-17538018-jpg/images/pdf_icon.jpg) (PDF, 256kb)     | ## Overview |   | | --- | --- | | **Description:** | The RAM 31-SP shot peening machine gives you a spacious dustfree direct pressure capability to efficiently peen small and large workpieces.  Engineered for shot peening media, the RAM 31-SP gives superb shot peening performance with outstanding flexibility. Built for rugged, continuous applications, the self-contained system can easily handle three-shift operations. Designed for cost-effective operation, the reclaiming section yields optimum production life from each pound of peening media by automatically recovering, cleaning, and reclaiming media. | | Function | Dry paint stripping | | Media | PMB (Plastic Media Blast) or Starch Media Blast | | ## Advantages |   | | --- | --- | | Powerful, fast, efficient cleaning and finishing: | Built for non-stop production, the RAM 31-SP cabinet provides the optimum in heavy duty peening performance. | | Reclaim media - reduce costs: | Fine tuneable reclaiming of media yields optimum production from each pound of shot. After striking the work surface, media and dust fall through the work deck and are pneumatically conveyed to the reclaiming section for cleaning.  Inside the reclaiming section a controlled cyclonic action spirals the media and debris, throwing good shot particles to the outer walls, where they spiral down through a dual adjustable air wash system offering independent controls for air wash volume and velocity, which enhances the separation of dust and fines from the reusable media.  A vibrating screen below the air wash traps oversized debris, allowing correctly sized, reusable shot to pass through to the storage hopper. Dust and fines are pulled from the center of the cyclone and the airwash and pneumatically conveyed to the dust collector.  Each time blasting stops, the pressure vessel is automatically refilled with clean reclaimed shot. | | Direct pressure blasting without interfering with other operations: | The RAM 31-SP shot peening machine provides a self-contained, highly productive blast area that does not pose a hazard to the environment. Compared to suction systems, the direct pressure blast generator of the RAM31-SP provides double the productivity with superior intensity control and repeatability. Surface finishing operations including deburring, deflashing, peening, etching, stripping and cleaning can go on around-the-clock without interfering with other operations or personnel. | | Optimum working environment improves productivity: | We improved your working environment so you can improve productivity. Brilliant lighting allows operators to work more productively on small components as well as large parts. 260 footcandle (280 dekalux) lighting level at the cabinet floor provides exceptional light for exceptional operator performance.  What’s more, working in hard to reach areas is easier as a continuous rush of fresh air sweeps through the cabinet providing excellent visibility. Dust laden air is carried to a set of dust collector cartridges for high efficiency filtering. Cleaning is via reverse pulse air jet.  The large 60”W x 48”D x 36”H (152 cm x 122 cm x 91 cm) blast chamber accommodates a wide variety of workpieces. And to increase productivity, many accessories are available. | | Operational Durability: | Shot peening is a demanding process requiring equipment having the strongest and highest quality engineering design, manufacturing methods and materials. A RAM 31-SP and accompanying parts and accessories will give trouble-free service under high production operation 24 hours per day, every day of the year for decades.  For sustained steel shot peening applications, the RAM 31-SP is an efficient, reliable, very low maintenance, unfailingly trustworthy machine. | |   |   | | ## Features   | | | --- | --- | |   **Features:** | • Dust free.  • Complies with latest regulations (as of 1991) from California South Coast Air Quality Management District (SCAQMD), Rule 1401, requiring “T-BACT”, Best Available Control Technology for Toxics. (The California SCQAMD is, to our knowledge, the most stringent AQMD in the nation.)  • Significant reduction in cost and time of peening compared to suction machines.  • Designed specifically for shot peening blast media, metallic and non-metallic. Also functions superbly with glass, aluminum oxide, and other abrasives.  • Newly engineered from the ground up for maximum blast and media recycling efficiency.  • The only machine with smooth, non-pulsing media flow for process repeatability.  • External vacuum return, dust free, closed cycle gun option allows peening of parts outside cabinet.  • Many other options and features. | ## [Request Information](https://www.paulisystems.com/contact/?hsLang=en-us) | Product Specifications   | | --- | | Stock Number   494-070-31 complete cabinet shot peening system with   Overall Cabinet Dimensions (w x d x h)   65 x 49 x 76 in 165 x 125 x 194 cm   Overall Power Pack Dimensions (w x d x h)   63 x 40 x 91 in   Shipping Weight (Two Pallets)   1500 lb 682 kg   Shipping Cabinet Dimensions (w x d x h)   71 x 55 x 81 in 181 x 140 x 206 cm   Shipping Power Pack Dimensions (w x d x h)   46 x 72 x 94 in 117 x 183 x 239 cm   Work Compartment (w x d x h)   60 x 48 x 36 in 152 x 122 x 91 cm   Door   Counterbalanced doors (Optional) Two hinged doors (Standard)   Door Opening (w x h)   41 x 36 in 104 x 78 cm   View Window   10.5 x 22 in 27 x 56 cm   Ventilation   840 CFM (23.8 CMM) 14 air changes/minute   Lighting   3 each, 150 watt incandescent. 260 footcandles (280 dekalux) at floor   Compressed Air Requirement   With 1/4" (6.4 mm) nozzle and vibrating screen: 44-51 CFM @ 100 psi (1.3-1.4 CMM @ 7 bar) With 3/8" (9.5 mm) nozzle and vibrating screen: 80-146 CFM (2.3-4.1 CMM) With 5/16" (8 mm) nozzle and vibrating screen: 66-77 CFM (1.9-2.2 CMM)   | | Reclaimer   | | Air Volume   840 CFM (23.8 CMM) recovery and reclaim   Storage Hopper   1.5 ft² 42 L   Vibrating Screen   Consumes 4 CFM @: 100 psi (0.11 CMM @: 7 bar)   | | Blast Generator   | | Diameter   14 in 36 cm   Bottom Cone   60 degree included angle with media fluidizing bed   Volume   28 L 1 ft³   Foot Control Door Interlocks   RC100P, Lo-Pro Feathertouch®   Door Interlocks   Included to prevent blasting with cabinet door open.   Moisture Separator Air Pressure   3/4" (19 mm) NPT with manual drain   Regulator   3/4" (19 mm) NPS, remote controller and gauge mounted on cabinet control panel   Shot Flow Valve   Shot peening media feed tee with easily changeable orifices   Aeration   Media fluidizing bed assures smooth non-pulsing media flow, in conjunction with 60° cone and straight media flow   | | Dust Collector   | | Volume Rating   840 cfm 23.8 cmm   Filtration   2 cartridges, each 225 ft² (21 m²) - total 450 ft² (42 m²) of filter area   Filter Cleaning   Reverse pulse air jet cleaning activated via pulse controllers on cabinet control panel   | | Motor/Blower   | | Motor   2 hp, 3450 rpm, TEFC   Electrical   Standard 208-230/460 volt, 3 phase, 60 Hz Optional   Motor Starter   Manual in NEMA 1 enclosure   Motor Current   6.0 - 5.6/2.8 amps, 60 Hz.   | | Options   | | Options   Highly recommended for all machines for ease of part handling during blasting is a 28” (71 cm), 500 lb (227 kg) base mounted turntable For heavy parts counterbalanced doors recommended with these options  • Work car and inside track: provides a mobile base for turntable, 1000 lb (455 kg) capacity  • Turntable: 40” (102 cm) diameter, 1000 lb (455 kg) capacity, base mounted  • Track extension: 6 ft (2 m) of outside track to ease loading of parts   Other Options   • Rubber lined HD cyclone.
