3-001 Noise and Dust Emissions Values
Noise
The noise emissions, according to EN31202 with CEN TC 142 and in relation to the reported ISO 7960 noise
emissions, determine the work place emissions ratings.
LpA = 93,8 dB(A) during drilling
measuring uncertainties constants K are 4 dB/A
The machine’s specific settings during the measuring cycle:
Drillbit: 1 Hinge cup drill bit Ø 35 mm t = 13 mm n=2890U/min.
2 Dowel drill bit Ø 8 mm t = 13 mm n=2940 U/min.
Work piece: uncoated particle board
Microphone’s position 0.5 m in front of the drill motor axle in 1.5 m height
Dust:
The determined dust rating accoring to DIN 33893 Part 2
Statistical protected maximum amount 0,48 mg/m3
Description of the interface exhaust connection piece:
Suction exhaust pipe
Ø 80 mm
Minimum air speed 17,9 m/sec.
Static suction 480 Pa
Connection of the Suction System:
The Ecopress must be connected to a suction system according to the interface description.
Hook-up line are to be very inflammable
If an electric coupling is required for the suction system, the Grass company has a special accessory-a volume flow
monitor with the appropriate contacts which are connected as shown in the electrical wiring diagram in chapter 4-007.
Suction Elements:
If the dust and shaving collection elements of the Ecopress system are correctly operated (hook-up according
to interface description), the amount of wood dust falls below the TRK limit values.
The testing procedures for measuring are set forth in the DIN 33893 Part 2 by an independent agency.
