The FIT® System uses low- NOTE: Varying angles of impinge- pressure impinging ment allow for pattern development at streams to bregk res¡n ¡nto J r large droplets after mixing. Large droplets improve the saturation of roving because they have stronger penetration force than small droplets. Low pressure impingement also reduces air entrapment so rollout can be done quickly. The result is a strong, flawless laminate, produced with minimal waste and emissions. ^MAGNUM VENUS PRODUCTS FIT® Pumping System Start with the lowest pressures. From the new low-pressure Powerhead/Fluid Section to the new gun and nozzle designs, MVP removed all of the obstacles to low-pressure operation with FIT®. The unique 2-hole tip design creates a sheet when the two streams intersect. The sheet carries forward and breaks up into ligaments which then break up into large droplets. FIT® works at power ratios of only 3:1 or6:1, eliminating spray atomization. Systems with power ratios of 11:1 and over will produce high levels of atomization, essentially changing the system from impinge to atomized spray. During testing, tip fluid pressures as low as 15 psi were recorded using the Cipher Gun. These low pressures have many benefits to the The lower pressures of the FIT® system allows the operatorio move closer to the part, resulting in less over-spray and dramatic material savings. Lower pressures require less air consumption, and will increase the life of the resin and catalyst pumps, shafts and cylinders. Lower pressures in the gun will also increase seal and tip life. Government Environmental agencies around the world are constantly re-evaluating the EPA standards and allowable styrene emissions levels for FRP manufacturers. Many are told to lower their emissions or cease operations until they can. In an effort to meet the ever-changing standards, manufacturers turn to new technology for the answer. FIT® has been proven to be that answer. Several independent tests have shown that FIT® has the lowest emissions in the Another benefit to FIT® systems is a substantial material and time savings for the manufacturer. With the lower pressures there is less resin used, a reduced amount of waste material The versatility of a FIT® system allows individual manufacturers to customize their processing equipment to address varying mold size and complexities, and is the most cost-effective means for reducing styrene emissions currently Resin Inlet FIT® impinge pattern on a 3:1 pump at 20 psi. Note lower pressure vs. competitor pattern pictured on the next page to achieve identical pattern width, and"defined wave" pattern continues nearly to target with a Competing Technology Competing nozzles require excessive pressures to develop patterns. True low pressure fluid impingement produces patterns that are 50% wider at a fraction of the pressure with less overspray. Competitive nozzles use 3 streams instead of 2 resulting in a loss of impingement energy at impingement point. Additionally, an 11:1 pumping system is used - high internal fluid pressures result in higher fluid exit pressure and atomization. FIT® Reports Lowest Field Tested Emission Factor Independent laboratory and field tests have demonstrated Magnum Venus Products as the leader in innovative, price-conscious solutions to VOC emissions. MVP FIT® has the only documented field tests on styrene emission rates.

Note pattern degredation and atomization begins almost immediately. Styrene Emission Factor based on Raw Material Usage (lb styrensJIb resin) In a recent independent field test conducted by order of a state environmental agency in the United States, emission factors with an average emission level of 4.1% were reported for an FRP manufacturer using the newly patented Fluid The state required the manufacturer to conduct independent tests measuring styrene emissions for conformance to EPAstandards. The manufacturer produces large underground storage tanks using polyester resins that contain liquid styrene monomer. The test was conducted on the production of four different underground storage tanks ranging from an 8' - 10' diameter mold, utilizing four complete MVP SuperFIT units with This stack test, conducted over two days in April, 2001 with 10,000 pounds of resin used, determined the styrene emission rates from four different UST molding stations. The calculations showed the quantity of styrene emitted per pound of styrene monomer consumed, and the quantity of styrene emitted per pound of raw resin consumed. In the only documented field tested measurements available today, emission levels as low as 2.2% were measured. The test method employed was the revised EPA Method 18, incorporating NIOSH Method 1501 absorption tube collection, and the new dual train "spiked" and "unspiked" recovery factor procedures. In general, the Method 18 approach used standard procedures to measure the exhaust stack flow rates with a pitot tube/manometer The charts show the test results computed from the styrene source testing data.
