Improving Your Electrostatic Liquid or Powder Coating Process
In this video, Air Power Specialist Travis Stirewalt and Account Manager Eddie Rhodes, share tips about improving your electrostatic process. Learn how to improve your electrostatic process with expert advice for powder coaters and liquid painters. Discuss best practices that help you put more powder or paint on your parts and less in your filters or the paint booth floor. What does this mean for you? Higher transfer efficiency and less paint (money) wasted by increasing your first pass transfer efficiency. Video from the Air Power, Inc. Chattanooga Branch.
Manufacturing facilities in today’s competitive market strive to produce the highest quality product. In this case study we will discuss the importance of recognizing every company’s desire to produce a premier product with the highest first place transfer efficiency.
A Custom Fabricator, producing products for the truck & and Bus industry
In order to distinguish them within the marketplace, the current manufacturing process needed to meet customer’s mil specs. Their current Powder Units were not producing enough Mils per MFG spec with a Quality finish. Examination by quality control engineers revealed that they were getting back ionization and orange peel when applying more powder and second coats. They determined that each operator had different settings and too much powder output. In addition they did not understand current and voltage and how they relate to a quality finish and high transfer efficiency.
In partnership with the customer, Air Power implemented an Gema OptiFlex 2 manual powder unit. The unit comes with 3 presets: 1: Flat Parts, 2: Recess/complex parts and 3: Recoat mode. In addition these cannot be changed by the operator and allowed ease of use with a simple repeatable process. The Patented Digital Valve control allowed for consistent precise powder output, powder savings, and reproducible coating results.
Currently, the customer is meeting their mil spec and producing repeatable results and has increased there transfer efficiently that has provided a 1 year Return on equipment investment.
Dedicating Your Powder Hose
Dedicating your powder hose specific to your color and special type of powder can save you time in color changes and prevent costly rejects. It can speed up your paint process, eliminate powder contamination and reduce clean up time. If you are frequently changing your powder color throughout the day, this is a great way to quickly and easily eliminate pain points and improve your application process.

Cartridge Filters for powder booths, blast booths, dust collection and smoke eaters is essential to a clean operation. Learn details about cartridge filters and properly selecting replacements.
Introducing the NEW Gema OptiFlex Pro:
POWER. QUALITY. CONTROL.
The NEW Gema OptiFlex Pro is here. Air Power’s Travis Stirewalt shows off the OptiFlex Pro features and upgrades including the gun, control unit and the E-App.
Power: Maximum coating performance
The newly developed PowerBoost technology of the OptiFlex Pro series offers with the 110 kV the highest powder charging capacity in the powder coating industry while complying with safety regulations. The operator benefits from an outstanding coating performance.
Quality: Best application results
With OptiFlex Pro you coat extremely efficiently and with consistently high quality. The PCC (Precise Charge Control) mode regulates the spray current even in the lowest ampere ranges (0-10 μA) with the highest accuracy. This prevents overcharging of even the most demanding powders such as metallic powder and ensures the highest quality in thick film and multi-layer applications and recess areas.
Control: Master the application!
The new features of OptiFlex Pro also give you a technological edge. The Electrostatic App (E-App) with the integrated line management functions and service features make the coating process transparent and better controllable.
Gema OptiFlex Pro Series
POWER – QUALITY – CONTROL
The new generation of OptiFlex Pro manual units impresses with additional application performance due to the outstanding PowerBoost technology. With OptiFlex Pro, you easily process all powder types and coat complex parts in superior quality – all this worldwide and in the most difficult industrial environments. The use of the Electrostatic App is your first step into Smart Factory Automation and makes the manual coating process transparent.
Maximum Coating Performance
The first choice in manual powder coating
The OptiFlex Pro manual units are uncompromisingly and agilely designed for maximum industrial suitability and worldwide use. The intelligent and durable components fit perfectly together and form the powerful package for superior manual powder coating. The ergonomic and intuitive operation enables every user to achieve the best coating results at any time.
Safe technology for more power performance
The newly developed PowerBoost technology of the OptiFlex Pro series offers with the 110kV the highest powder charging capacity in the powder coating industry while complying with safety regulations. The operator benefits from an outstanding coating performance. The new feature completes the proven high-voltage functionalities, such as PCC mode, presettings an individual coating programs and extends the application range significantly.
highest industrial suitability
– The new OptiSelect Pro gun features a particularly robust and durable design. The ergonomic and light-weight gun is well-balanced in the hand, has a good grip and enables you to coat efficiently and faster.
– The new PowerBoost high-performance technology charges all types of powder even more efficiently. The benefits of the additional power provide higher productivity, faster conveying speeds and maximum area performance.
– The integrated remote control allows easily to activate the PowerBoost powder charging mode and to regulate the powder output right away.
– The integrated cleaning of the powder conveying components can be enhanced by the optional PowerClean module, which ensures a faster and efficient cleaning. This improves performance when processing difficult powders and facilitates colour change.
– The latest generation of nozzles ensures an excellent powder distribution and penetration.
Best Application Results
Be one step ahead of the competition!
With OptiFlex Pro you coat extremely efficiently and with consistently high quality.
The PCC (Precise Charge Control) mode regulates the spray current even in the lowest ampere ranges (0-10µA) with the highest accuracy. This prevents overcharging of even the most demanding powders such as metallic powder and ensures the highest quality in thick film and multi-layer applications and recess areas.
The DVC (Digital Valve Control) technology allows an exact and repeatable adjustment of the powder output and ensures an uniform layer thickness.
for repeatable quality
The new OptiFlow injector with cartridge design further optimises the venturi principle in terms of transport efficiency and low wear. By simply exchanging the one-piece cartridge, the injector performance is optimally maintained. The usage of fewer parts and the seamless design of the injector improves the ability for fast color changes.
Main features OptiFlow injector:
-Cartridge design merges injector nozzle and conveying insert into a single component
