Product Code: 929

The Spectra Precision 929 heavy-duty blower is used to improve the performance of pipe lasers when shooting through the pipe by equalizing the temperature and air density inside the pipe. Operate off of a separate 12-Volt DC automotive battery to power the blower.

Operating Instructions:

Use a separate 12-volt automotive battery to power the blower. Point the nozzle into the pipe to create a corkscrew effect. This is the most effective way to create temperature stabilization. Ensure the air intake is not blocked and the 929 is not set in water. The support handle/cord wrap bracket is on the opposite side of the air intake. This handle can hook over a manhole step to keep the unit out of water in the pipe. Start the blower with the first section of pipe. Use the table on the blower to determine the blower speed from the length and size of pipe being installed. Although very unlikely, be aware too much air can also cause refraction.
  • Variable speed
  • High capacity output minimizes beam refraction to prevent beam bounce and grade sag
