DigiVac FYRA-Bleed Valve Bundle

Brand :



FYRA Digivac Bleed Vacuum Controller for venting or bleeding in gases like room air, argon or nitrogen during vacuum processing applications. Increases molecular flow and speeds up vacuum drying.

  • FYRA Bleed Vacuum Controller —This bundle is set-up to allow for distillation applications like short path, freeze-drying, vacuum drying and other vacuum application that would benefit from the increase of molecular flow that you get from the bleeding of gases into your system.
  • Bleed air or other gases (like nitrogen or argon) into your system to control and maintain the vacuum level. This application can help you speed up the drying process.
  • See an example of FYRA Bleed Control here. | Showing the flow varying in order to maintain a 0.5 Torr Set-point
  • Benefits of Bleed Vacuum Control—The bleeding of gases into a distillation process helps increase molecular flow which increases throughput which helps improve quality of distillate by avoiding additional time and oxidation in the boiling flask
  • Rich remote command line interface enables the user a high degree of remote control and monitoring from any computer
  • Bleed Vacuum Control also helps increase molecular flow and throughput
  • Calibrated—Every FYRA is calibrated and pretested under actual vacuum against a NIST standard (Need NIST traceable documentation? Add this option to your order)
  • Applications—Ideal for introducing gases under vacuum in botanical processing to increase molecular flow, Freeze Dryer recipe control, Short Path Distillations, and Plasma Treatment Control
  • Use Case Example—A manufacturers wants to control their freeze drying process better, so they implement this vacuum measurement and control solution to maintain 300mT in batches to improve consistency, and can view the ongoing process from any browser by accessing 
  • Measurement Range: 1 mT to 760 Torr
  • Accuracy Range: 1 mT to 6 Torr (need accuracy in a different range of vacuum? This configuration can be easily modified to include different sensors)
  • Bleed Control Range: 10 mT to 6 Torr


  • Mass Flow Controller for Vacuum
  • Micro-dosing
  • Gas Mixing
  • Catalyst for increased molecular flow and faster vacuum drying
  • Microscopy

FYRA Bleed Vacuum Controller Components:

3 Simple Steps for Vacuum Process Set-up with FYRA Vacuum Controller:

  1. Plumb the vacuum gauge(s) and valve into your vessel
  2. Connect the sensor, power, and I/O cables into FRYA
  3. Measure and control vacuum

FYRA/StrataVac Software: Connect USB port to laptop to take advantage of StrataCapture Software for data logging. 

  • WiFi connected data can be used on any browser by connecting to to display, graph and log vacuum data

Warranty Policy

Every gauge that leaves DigiVac is tested under actual vacuum and calibrated against a NIST standard. We warranty all gauges for workmanship and function for 1 year.* Each vacuum instrument has a serial number, which allows us to track the age of the gauge. Any gauge will be repaired and returned free of charge for any defects in workmanship or function, FOB Morganville, NJ.

Any gauge that becomes damaged (for example: tube contaminated, flashback or physical damaged) may be returned to DigiVac for repair at a time and materials rate. Please contact Digivac with a request for Return and an RMA number will be issued. A decontamination form will also need to be filled out.

Note: Sensors (also known as tubes or probes) are not covered under this manufactures warranty. These are classified as consumables.

Customers are responsible for handling shipping charges to and from our facility in New Jersey.
