Description

SNAP Vacuum Controller | Simple, Nimble, Automatic Process Controller

The SNAP Vacuum Controller delivers precise vacuum measurement, control, and venting in one integrated system—designed to automate and simplify vacuum processes without compromising flow performance. Featuring a patented dual proportional valve, intuitive controls, and programmable recipes, SNAP provides reliable, repeatable vacuum regulation for laboratory, industrial, and research applications.

New features: Faster Venting with external valve, More steps per recipe (now 80) for evacuation purge cycles, and PLC control with Analog output

Why SNAP?

SIMPLE – Push-button control replaces manual vacuum management
NIMBLE – High flow design maximizes throughput and speed
AUTOMATIC – Programmable recipes deliver repeatable, precise processes

SNAP: Automatic Vacuum Process Controller | Vacuum control and venting with the touch of a button or twist of a dial

All-in-One Vacuum Control

Integrated measurement, control, and venting
Patented dual proportional bellows valve for both throttle and bleed control
KF25 vacuum interface with high-flow 20 mm path

Simple, Intuitive Operation

7” touchscreen with large numerical display and real-time graphing
One-touch pushbutton controls: Vent, Close (isolate), Full Vac
Fast setup and minimal training required

Advanced Recipe Control

Store up to 10 recipes, each with 80 programmable steps
Time- and pressure-based control with Ramp or Hold modes
Full recipe control: Play, Pause, Stop, Rewind, Skip

Precise Process Control

Setpoint control using both vacuum and controlled venting
Faster convergence to setpoints with stable PID control
Gentle ramping ideal for sensitive processes like drying and lyophilization
Vent your vacuum chamber or equalize your system with the touch of a button instead of pulling hoses or turning valves
Dashboard pushbutton control for START, STOP functionality for each channel allows you to automatically vent or isolate your system with a push of a button

Ideal for automating and simplifying vacuum chamber pressure control.

Vacuum Flange: KF25 (KF40 with external valve option)
Measurement Range: 1 Torr to 775 Torr (standard)
Control Range: 2 Torr to 760 Torr
Integrated Sensor: Isolated Piezo sensor
Need millitorr range?: SNAP has a RJ45 Port for adding an additional sensor to extend the measurement range. We recommend the addition of the DPP Quantum to be able to monitor and control from 0.01 Torr to 1000 Torr.

Precise Flow and Process Control

SIMPLE – SIMPLIFY YOUR LAB & CONTROL MORE WITH LESS

Replaces manual valves and hose adjustments with automated control
Enables use of rotary vane and dry scroll pumps in place of diaphragm pumps
Keeps pumps operating near base pressure for extended lifespan

NIMBLE – MAXIMIZES THROUGHPUT & PUMPDOWN SPEED

Large internal flow path (20 mm) for faster pumpdown and evaporation
Optional external vent valve (up to 40 mm) for accelerated venting and pumpdown
Time-Based Vacuum Differential Control for dynamic performance optimization

AUTOMATIC PROCESS – PRECISION CONTROL & INTUITIVE DESIGN

Analog In/Out (0–10V) for PLC integration and external control
USB and optional RS232 or WiFi for remote monitoring and automation
Compatible with DigiVac software tools for data logging and process visibility like RS232 logger, Stratacapture and the Torch data logger
Real-time monitoring via PC or cloud-based platforms

SNAP Wetted Material:

304 Stainless Steel
316 Stainless Steel
PTFE
Viton

Applications

Vacuum ovens and vacuum drying
Freeze drying / lyophilization
Thermal vacuum (TVAC) testing
Rotary evaporators
Powder drying and API processing
Battery and materials research
Composites and food processing
Vacuum chambers (1L to 1000L+)

External Valve Control (Optional)

Optimize venting and pumpdown speed with Time-Based Vacuum Differential Control:

Automatically actuates external valve if setpoint is not reached within a defined time
Adjustable parameters:
- VD (Vacuum Differential) – allowable deviation from setpoint
- VDW (Time Window) – time allowed to reach setpoint
Improves efficiency and cycle time without overshoot

Calibration Services

All vacuum instruments that leave the DigiVac factory are calibrated under real vacuum against a NIST standard. If you would like to have your SNAP Vacuum Controller Calibration Information please add either of the following items to your cart.

NIST Calibration
- Vacuum Gauge or Vacuum Controller NIST Calibration with traceable data, which ensures that vacuum measurement readings are accurate. NIST calibration is recommended on an annual basis.
- NIST calibration involves using a higher accuracy vacuum gauge calibrated by an A2LA certified lab to the vacuum gauge being tested.
Calibration without Documentation
- Controller or Gauge Calibration without Data (no documentation is provided). DigiVac recommends yearly calibration of your vacuum gauge or controller.
