Flow tester 3240E-F-G

pressureair permeabilityfor paper

Product overview
AIR TRONIC PLUS is a fast and silent electronic instrument to determine the air permeability (meant as the speed of the airflow vertically passing through the sample under preset and known testing conditions) of woven, knitted and non-woven fabrics, industrial fabrics for technical use, artificial leather, felt, velvet and paper. It can also calculate the average pore size of woven fabrics, a unique feature important for filtration.

Air permeability range
Thanks to the different testing template areas supplied with the instrument, the air permeability range is extremely wide and goes from a minimum of 1.4 mm/sec up to a maximum of 8056 mm/sec (for some models / configurations ranges extend further as described in specifications).

Equipped with

• wheels
• touch-screen display
• built-in suction unit with cooling system with high noise reduction
• digital Flux Meter (to perform fast tests)

Accessories (examples)

• Medical Mask Testing Kit (optional)
• Data Management Software (available on demand)
• PLC Software for average pore size calculation (available on demand)
• Built-in micro printer (available on demand)
• Automatic Pressure Drop Regulator (available on demand)
• Seal Fixing Rings (available on demand)
• Template Area Adapter (available on demand)
