Description
Dwyer 2005 Magnehelic Differential Pressure Gauge 0-5 In WC 15 PSIG Max
The Dwyer 2005 Magnehelic is a low-range differential pressure gauge measuring 0 to 5 inches of water column (In WC) with a maximum rated pressure of 15 PSIG. It uses Dwyer's well-known Magnehelic mechanism — a frictionless, helix-spring-free design that translates differential pressure into needle movement via a precision magnet and coiled spring, requiring no liquid fill and offering fast, accurate readings with minimal maintenance.

Applications
The Dwyer Magnehelic series is one of the most widely used differential pressure gauge lines in HVAC, cleanroom, and industrial air-handling applications. The 2005 model's 0–5 inch water column range is well suited for monitoring static pressure across air filters, measuring duct static pressure in ventilation systems, and verifying pressure differentials in cleanrooms and laminar flow hoods — environments where maintaining a controlled positive or negative pressure relative to adjacent spaces is critical. These gauges are standard on air handling units (AHUs), rooftop units, and fan coil systems to signal when filters have become loaded and require replacement. They are also commonly used in laboratories, hospitals, and pharmaceutical facilities to monitor room pressure differentials. The Magnehelic design operates without fluid, eliminating the mess and evaporation concerns associated with manometer tubes, which makes it a practical choice for permanent panel installation.
This Dwyer 2005 Magnehelic differential pressure gauge has been visually inspected and appears to be in good used condition. The dial face is clean and legible, with the needle resting at zero. The housing shows light surface wear consistent with prior use, and both brass barbed pressure ports on the rear are intact. It has not been powered up or bench-tested at our facility, but appears to have been pulled from a working environment. Please view our photo set and contact us if you have any questions.
