1 General Notes Netter pneumatic piston vibrators series The drive medium is compressed air or NTP comply with the EC machine nitrogen, at a pressure of 1 bar to 6 bar. directive 98/37/EG. Standards DIN EN Series NTP pneumatic piston vibrators ISO 12100 part 1 and part 2 have been can be used for food production and in particularly observed.
Page 4: Technical Data
2 Technical Data Drive medium: Clean (5 µm filter), lubricated compressed air or lubricated nitrogen Unfiltered compressed air will lead to breakdown of the vibrators. Operating pressure: 2 bar to 6 bar The operating pressures must not be exceeded or fallen short of. Timed operation is compulsory for NTP B+C vibrators (e.g.
Page 5 noise level pressure exceed dB(A), dependent on the surface upon which depending on the mounting surface it is mounted. As a rule, the noise level and the pressure. of the NTP 25 B (with silencer), at an hard-impacting installations operating pressure of 6 bar, lies below (without base plate), the noise level 80 dB(A).

3 Design and Function The vibration is generated by a freely If the device is required to produce oscillating differential pressure piston. hard impacts, either a steel plate is inserted into the base plate or the base In the basic version NTP B+C, the plate is completely removed.
Page 7: Safety
4 Safety NTP vibrators operate using compressed air at a pressure of up to 6 bar. All hoses must therefore be securely connected. pressurized hose becomes loose it can cause injury. The compressed air must therefore be shut off before performing installation work. Jan.
Page 8: Transport And Storage
Drive medium: Clean (5 µm filter), lubricated compressed air or lubricated nitrogen Unfiltered compressed air will lead to breakdown of the vibrators. Operating pressure: 2 bar to 6 bar The operating pressures must not be exceeded or fallen short of. Ambient temperature: Standard 5°C to 60°C The operating temperatures must not be exceeded or fallen short of.
Page 9: Installation
6 Installation During installation, the safety regula- tions in chapter 4 and the safety pre- vention rules must be strictly observed! Ensure that the compressed air supply is shut off during installation or when working on the vibrator and air supply lines.
Page 10 The above diagram illustrates the possible applications: On vibration tables, for compaction, testing, etc. Under tables, on filters, for shaking, etc. On hoppers, for emptying, on vibrating troughs and sieves. Use lock screws and nuts and a liquid adhesive (e.g. Loctite) to prevent loosening.

Page 12: Start-Up / Operation
Checklist for Installation Consider the expected operating temperature. Mount the unit. Secure fastening screws. Install the service unit (filter, mist lubricator, regulator, as required), valve and supply line. 7 Start-Up / Operation The start-up of the vibrators is possible „AIRPRESS 15“ oil for operating immediately after correct installation.
Page 13: Service, Maintenance
When using dried compressed air and under extreme environmental conditions, installation upstream mist lubricator is compulsory. Regulation of Amplitude: Regulation of Frequency: The amplitude can be regulated by The frequency can be regulated by throttling the exhaust air (throttle fitted reducing the air pressure before it in air discharge line).
Page 14 Before starting inspection or service work, shut off the compressed air supply and protect it against unwanted activation! Jan. / Feb. / ... Regularly check the attachment of the vibrator, the compressed air supply and upstream service unit, as well as the silencer –...
Page 15: Troubleshooting
9 Troubleshooting Fault Possible Cause Remedy Will not start Silencer Clean silencer Compressed air supply Check pressure on device! Is enough pressure available? Check valve. A 3/2 way valve is compulsory, so that the supply line to the device is vented. Cover loose An unsealed cover causes standstill Tighten screws.
