SERIES 2000 MAGNEHELIC® DIFFERENTIAL PRESSURE GAGES
Indicate Positive, Negative or Differential, Accurate within 1%
No Power Required
Low Cost
Used in Isolation/ Hospital Environments and Temporary Units (no power required)
Select the Series 2000 Magnehelic® Gage for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Select the -HA High Accuracy Magnehelic® Gage option for an accuracy within 1% of full scale, located below in the Product Configurator. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.
NIST CALIBRATION available.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
Series AT-2000 for ATEX approved.
California Residents: Proposition 65 WARNING.

Delta P & Delta P Plus Control Panel
Delta P & Delta P Plus Control Panel
Donaldson Torit Delta P & Delta P Plus Controls
These Controls are solid-state products providing pressure drop measurement, digital display, and pressure drop control with an alarm function. Designed to provide accurate and dependable control of a pulse-cleaning timer, starting and stopping the cleaning process at the limits you choose. The Delta P and Delta P Plus are available as standard equipment on the Downflo Oval, Downflo II, Downflo WorkStations, Dalamatic, Modular Baghouse, and Electrical Control Panels
Process Environments can custom design the appropriate control panel for your system requirements.
For general ventilation systems, it may be advantageous to interlock specific fans for different areas of the building.
