Retrotec 451 Commercial DucTester

The Model Retrotec 451 is simply a Model 441 with an adapter that fits to the front of the fan. Change the test direction by moving the 100 mm flex from the outlet to the inlet adapter which snaps on in one second. No clumsy flanges to disassemble.

Test to 250, 1000 or even 5000 Pa! Sufficient flow for almost every test. 600 square meters of duct or more can be tested.

Results in any desirable unit such as cubic meters per second per square feet is read directly off the gauge. Or, use the test to complete and automated test then have the software generate an EN12237, FE E51-767 or DW/143 compliant report that can be easily customized with your format, logos and even pictures of the test. Users love the set up and test speed.
