| E3-A-DM4-110/60 |
Infiltec Digital Blower Door
includes a fiberglass fan,
aluminum door panel with nylon cover and case,
DM4 Micro-Manometer, controls, calibration certificate, manual & case.
The DM4 Micro-Manometer features digital flow and pressure measurement,
leakage area (ELA) measurement, and dual auto-zeroing sensors for simultaneous
flow and measurements. The resolution is 0.1 Pa and 0.001" wc,
the range is -3.0 "wc (750 Pa) to +2.2 "wc (548 Pa),
and the pressure accuracy is 1% of reading or 1 digit.
The DM4 is calibrated for use with the E3 blower door, the Infiltec
DL1 duct leakage tester, and Pitot tubes. Flow, pressure, and leakage
area can be displayed in US, metric, or mixed units. Electronics are
110VAC/50 Hz. Options include software, fan covers, and door expander kit.
NEW FEATURE: digital display of building leakage area in square
inches/centimeters at any test pressure.
Specifications
Picture
The E3 is designed for testing residential and small commercial buildings.
For example, it can test buildings up to 3,500 ft2 by 10 ft (325 m2 by 3 m)
with leakage up to 10m3/h/m2 or 8.9 ACH @ 50Pa.
For testing larger buildings, see the Large Building Air Leakage Test Calculator
to determine how many E3 fans are required.
