Great coating quality and powder savings The smooth powder delivery improves the application, which remains constant for a long time thanks to the wear-free technology. Reduced powder consumption © 2015 by Gema Switzerland GmbH - All rights reserved. Improved application quality

Smart Inline Technology: how does it work? Vacuum sucks a powder packet into the Main Chamber. Transportation Air Second Chamber Second Chamber Open pinch valve Main Chamber Main Chamber Closed pinch valve Transportation Air pushes powder to the Second Chamber and to the gun. Open pinch valve Closed pinch valve All this happens within 0.33 seconds! © 2015 by Gema Switzerland GmbH - All rights reserved.

Smart Inline Technology: how does it work? • With Smart Inline Technology powder output remains constant for a very long period of time. • There are no wearing parts whose deterioration can decrease the powder output. • Periodic maintenance is recommended for just a few components. • Self-detection system identifies failures of key components. © 2015 by Gema Switzerland GmbH - All rights reserved.

Smart Inline Technology: how does it work? ● Powder is conveyed from the AP01 pump to the gun using only little compressed air. Ideal powder atomization and charging Dense, low velocity transportation in small hoses ● Powder hoses are smaller in diameter and easier to manage. ● Powder velocity in the hoses is lower, reducing wearing problems. ● Longer powder hoses can be used without the need for more transport air. ● Optimal amount of air for powder atomization is added just at the back of the gun. © 2015 by Gema Switzerland GmbH - All rights reserved.

Traditional Venturi Technology ● Nozzle blows air into the injector sleeve ● This creates depression in the injector chamber that sucks powder from the fluidized hopper ● Powder + air is conveyed to the gun ● Powder progressively wears out the injector sleeve: as injector sleeve wears out, performance decreases! ● Large powder output requires more air through the injector nozzle: possible application problems, lower transfer efficiency! © 2015 by Gema Switzerland GmbH - All rights reserved.

Traditional Venturi Technology Injector performance rapidly decreases as injector sleeve is wearing out Initial powder output is kept higher than needed to compensate future wear ("Safety Reserve") After replacing the sleeve powder output returns to the initial level Sleeve must be replaced when performance reaches the minimum level Problems: • Excessive powder output due to "Safety Reserve" => Powder Waste!! • Irregular film thickness due to sleeve replacement => Low Quality !! © 2015 by Gema Switzerland GmbH - All rights reserved.

Constant quality and powder savings ● The AP01 pumps thanks to their wear-free Smart Inline Technology can deliver constant powder output for a long period of time o No performance decrease due to parts wearing o Constant powder output over long time o Constant coating thickness o Constant powder savings o Repeatable coating result o Constant quality © 2015 by Gema Switzerland GmbH - All rights reserved.

Improved quality and powder savings ● Venturi Injectors need larger hoses and higher amount of air to transport powder. With AP01 pumps the powder is conveyed to the gun with just little air. Excessive air amount necessary with long hoses and high powder output can determine too high powder velocity at the gun nozzle. Optimal atomization air is added at the back of the gun. This allows softer and denser powder cloud even with long hoses and high powder output. Less efficient powder charging Ideal powder charging in all conditions Possible application problems Optimal application performance Reduced...

Improved quality and powder savings ● The AP01 pumps thanks to their Smart Inline Technology can transport high amount of powder to long distances with just minimum amount of air. o Easier optimization of powder application o Softer and more efficient powder cloud o Improved powder charging and transfer efficiency o More powder on the parts, less waste in the recovery system o Optimal application in all conditions o Improved coating performance © 2015 by Gema Switzerland GmbH - All rights reserved.
