XPT's New "Automatic" Duct Leakage Testers!
XPT "Automatic" Duct Leakage Testers
XPT introduces our Exclusive "Automatic" Duct Leakage Testers that are only available through XPT. Our latest automatic duct testers utilize a motorized variable inlet damper that is controlled through an adjustable pressure guage for easy setpoint adjustments to allow your tester to maintain your required test pressure settings. No longer is manual adjustment of your duct leakage tester is required. Our testers are designed for simple, "no fuss"operation. The DLT4-300A (4" tube), is our smallest tester for lighter testing requirements. The DLT5-600A (5" tube), is next largest tester that may be used on light to medium size duct systems. The DLT6-1200A (6" tube) and the DLT8-1800A (8" tube) are the largest of our testers which can be used on most medium to large size duct systems. Configuring our automatic duct leakage testers are the same simple operation as our standard models for use in either positive or negative duct pressurization testing which utilize our "Quick Seal" connection design. As with our standard models each connection consists of a heavy gauge rolled lip collars that are designed to precisely sit flush and seal with matching hose adapter connection. The connection is then quickly locked and securely sealed with a "Forever Clamp" from KBDuct. It is an "all welded" stainless clamp which is fitted with a heavy duty, continuously reusable O-ring sealing gasket which have no perforations to fatigue or tear. In fact the locking mechanism is so sturdy that KBDuct backs their clamps with a “forever†guarantee. See the following photos demonstrating XPT's "Automatic Vari-Tune" airflow adjustment and our "Quick Seal" connection design for configuring your tester for either positive or negative pressurization testing requirements.

"Global Warming" has become a serious issue involving everyone and everything including the HVAC Industry. As this threat continues, state and federal regulations are continually changing and becoming more stringent in their energy guideline design requirements for HVAC designers . Because of this, HVAC systems are being more closely scrutinized than ever before and will continue to be as long as global warming continues to be a threat. With changes constantly being implemented into HVAC design guidelines, duct leakage requirements can be expected to be less than 1 percent of the total system CFM design. To meet the challenges of these ever changing requirements, XPT offers a new generation of duct leakage testers to meet these new challenges that face contractors in the HVAC industry today and tomorrow. Our duct leakage testers were not only designed to be more advanced and efficient, they were also designed to be economically priced for almost any kind of budget. We guarantee our testers with a 5-year warranty and product support to ensure your testers continually operate and satisfy all your testing requirement needs. Our standard line of testers can accommodate a variety of usage, including residential. light commercial, commercial & industrial systems. See the following illustrations below which shows how our Duct Leakage Testers are used in a typical Duct Systems.

XPT's Differential Tubes were designed to meet the requirements specified by SMACNA HVAC Air Duct Leakage Test Manual; "Tester Guideline Requirements". Each tube is built from one piece, large gauge, welded seam galvanized steel tubes for long term durability and consistent operation of your duct tester. Each differential tube is matched with a specifically designed differential pressure flow sensor that reads the difference in pressure between the high "H" port and the low "L" port which is used to determine the air flow. The “H†port senses total pressure and the “L†port senses static pressure. The difference between these signals varies approximately with the square of the air velocity. This difference of pressure is measured with a manometer included with each duct leakage tester.
SMACNA Duct Leakage Test Manual
To help you along with your testing needs, every duct leakage tester comes with the latest testing standards from SMACNA. A companion to HVAC Duct Construction Standards - Metal and Flexible, this manual contains duct construction leakage classification, expected leakage rates for sealed and unsealed ductwork, duct leakage test procedures, recommendations on use of leakage testing, types of test apparatus and test setup and sample leakage analysis. Also covered are orifice flow meter design and valuable references for fluid meter instrumentation. This manual is referenced in ASHRAE's Energy Conservation Standard 90.1. Identified as DALT by some government agencies.
