Mass Flow Controllers for Inert & Aggressive Gases
High Vacuum and Pressure Applications
Can Your Mass Flow Controller Control 30 Different Gases? We Can!
Apex Mass Flow Controllers for vacuum and pressure applications combine flexibility with great accuracy. Our mass flow controllers are multi-gas capable with a flexibility to choose from a list of up to 130 on-board gases. We offer the option to choose your input and output voltage along with the ability to use RS232 data communications. Using the optional BB9-USB Communications Box our Apex Mass Flow Controllers can control up to 27 Apex devices through one RS232 port, providing your set-up the ultimate flexibility.

Types of Apex Mass Flow Controllers
Standard, Aggressive and Low Pressure Drop Models
Apex MFC for Vacuum
Apex Mass Flow Controller
Our Apex Mass Flow Controller is standard for most applications either vacuum or pressure. At Apex, we offer for the price the most accurate and also fastest MFC on the market. Options available to customize your mass flow controller for your specific application. You can add features/options such as high calibration, totalizer function, and custom VCR gas fittings. Our on-board controller allows you to set our MFC without expensive rack mount control boxes. Using our PID parameters, you can further customize the speed and update times to better meet your application needs.
Apex Mass Flow Controller for Vacuum Applications
Our Apex Mass Flow Controller for vacuum applications can be used in new systems or for replacing older mass flow controllers. Replace existing thermal mass flow controllers as ours is comparable form, fit and function. The enclosed valve design and fittings conforms to SEMI International Standards. Gas connections are VCR.
Apex Aggressive Gas Mass Flow Controller
The Apex Aggressive Gas Mass Flow Controller provides flow control of some of the harshest gas applications. Gases include ammonia, butylene, chlorine, dimeth ylether, hydrogen sulfide, silane and others. The Aggressive Gas Series uses alternative seals compatible with these and other aggressive/corrosive gases that normally are problematic with the standard Viton seals. Each Aggressive Gas Apex MFC does come with all inert and other gases in the library. Output connectors can be the standard NPT or welded VCR.
Apex Low Pressure Drop Mass Flow Controller
The Apex Low Pressure Drop Mass Flow Controller allows control of gas flow when the pressure differential is minimal or cannot be disturbed. This option can reach full-scale pressure drops as low as 0.06 PSID. When you have an application where keeping the pressure differential steady is essential or there is minimal pressure to work with, the Apex Low Pressure Drop Mass Flow Controller is the MFC for you.
