These tests allow single section louver heights up to 144". They also allows single section louvers on both models to be installed in concrete,wood and steel beam. It eliminates the need for expensive epoxy anchors in the concrete mounting.
This new testing now allows single section louvers to be installed with aluminum sleeves.
The testing for the EFD-637-MD and the ECD-545-MD models was done at Architectural Testing Inc. in Southlake, Texas. 5 louver sections measuring 48" x 144" were subjected to a static test of up to 225 PSF per TAS 202-94. They were then bombarded with a 9 pound 2" x 4" at 34 MPH at multiple points along its construction per TAS 201-94. The louvers were then cycle tested over 600 times with both negative and positive pressure up to 188 PSF per TAS 203-94.
Pottorff SPECs Update 126.96.36.199. Notice of reduction in cost of our Standard Color Baked Enamel finish. The reduction is a result of the addition of new finishing equipment that was installed in our recent building expansion.
