# Basic information

The technical data presented at the web site are based on extensive control measurements, performed in a laboratory with calibrated measurement equipment according to internationally accepted standards. The data are based on measurements performed under the following conditions:

**Feed pressure
**Feed pressure is measured right in front of the air nozzle, and is stated in the unit kilopascal [kPa] or pounds per square inch [psi]. Technical data presented in the manual apply at a feed pressure of 500 kPa (72.5 psi) unless stated otherwise.

**Blowing force
**Blowing force is measured on a scale with a flat surface of 310 x 290 (12.20″ x 11.40″) and at a distance of 200 mm (7.87″) from the opening of the air nozzle. Blowing force specified in the unit Newtons [N] or ounces [oz] or pounds [lbs]. 1 lb = 16 oz.

**Blowing force at different pressures
**The values for blowing force at 200 kPa to 1000 kPa resp. 40 psi to 120 psi.

**Air consumption
**Air consumption is measured by a flow meter located before the blowing nozzle. Consumption is given in the unit Normal cubic meter per hour [Nm³/h] or standard cubic feet per minute [scfm].

**Air consumption at different pressures
**The values for air consumption at 200 kPa to 1000 kPa resp. 40 psi to 120 psi.

**Sound level
**Sound level is measured at a distance of one meter (3.28 ft) from the air nozzle outlet and with the microphone perpendicular to the direction of the air jet. The sound level is stated in the unit decibel A [dB(A)].

**Sound level at different pressures
**The values for sound level at 200 kPa to 1000 kPa resp. 40 psi to 120 psi.

**Blowing pattern
**The blowing pattern shows the spread of the air in front of the air nozzle and is stated in millimeters [mm] or inches [“].

**Blowing pattern at different distances
**The values for blowing patterns from 50 mm to 500 mm and 4″ to 20″.

**Air velocity
**Air velocity is measured at the center of the air jet and is stated in meters per second (m/s) or feet per second (ft/s)

**Air velocity at different distances
**The values for air velocity from 50 mm to 500 mm and 4″ to 20″.

**Measurements
**The measurement data are stated in millimeters [mm] or inches [“].

**Temperature
**Maximum allowable working temperature for the products is stated in degrees Celsius [°C] or degrees Fahrenheit [°F].
