Netter vibrators find their application in almost all industrial fields. Besides the classic applications in the field of bulk material handling, we are continuously developing new solutions together with our customers, in order to improve production processes or introduce new applications. Each of the available vibrator types has its own specific features and it is often these features which make a solution at all possible. Some vibrators generate rotary vibration, while others generate linear vibration. For some types of vibrator, it is possible to adjust frequency and amplitude independently whilst running. Other devices exhibit special vibration characteristics. We also offer vibrators for explosive environments according to ATEX regulations and stainless steel vibrators for chemical and food applications. We supply vibrators with pneumatic, electric and hydraulic drives and are therefore able to solve almost every imaginable problem arising in production, conditioning and material handling, in most industries.
Netter Pneumatic Vibrators Features and benefits of Netter pneumatic vibrators and impactors : Low air consumption Frequency or impulse adjustable via air pressure Amplitude of linear vibrators adjustable via the exhaust ATEX or stainless steel versions available There are 3 different working principles: Rotary vibrators generate rotary vibrations Linear vibrators generate linear vibrations Impactors generate impulses The vibration characteristics of each vibrator are essentially defined by these 3 working principles. Rotary vibrators mainly generate high frequency vibrations with low amplitude Linear vibrators generate lower frequency vibrations with higher amplitudes Knockers generate impulses comparable to a hammer blow. Each of the 3 working principles has its own specific vibration characteristics. The respective application dictates which principle can be most effectively implemented. Our application engineers will be pleased to advise. Netter supplies solutions.

Netter Electric Vibrators Benefits and features of Netter electric vibrators: The driving energy is electricity Voltages from 12 Volt DC up to 690 Volt AC Frequency from 50 to 200 Hz or adjustable by means of frequency converters Rotary vibration Easy to clean, smooth surfaces Resistant to aggressive environments Special stainless steel versions and explosion proof versions according to ATEX regulations are available Netter electric vibrators are available as external vibrators and as internal vibrators. External vibrators are mounted to the structure to be vibrated (feeder, hopper discharge, precast form, etc.). Internal vibrators are placed into the product to be vibrated (concrete, bulk material, etc.), and are therefore subject to a certain amount of wear, due to abrasion from the product.

Netter Hydraulic Vibrators Benefits and features of Netter hydraulic vibrators: Rotary vibrations High working moments, large amplitudes Favourable power to weight ratio Variable frequency Netter hydraulic vibrators are available as external vibrators and as internal vibrators. External vibrators are mounted to the structure to be vibrated (feeder, hopper discharge, precast form, etc.). Internal vibrators are placed into the product to be vibrated (concrete, bulk material, etc.), and are therefore subject to a certain amount of wear due to abrasion from the product.

Netter ATEX-Vibrators NetterVibration has been supplying an extensive range of vibrators for use in potentially explosive areas, according to ATEX regulation 94/9/EC, since 2003. All of the devices comply with the requirements of this regulation. The ignition potential of each vibrator has been evaluated according to the formalised procedure of EN 13463-1. This results in a series of ATEX conforming vibrators with special application rules. Details can be found on the declaration of conformity or in the operating manual that comes with the vibrator. You should be aware that only vibrators showing a registration number or documentation number on their name plate can give you the certainty that the stipulated procedure for the evaluation of conformity has been conducted, and that the vibrator you have in your hand is really suitable for use in potentially explosive areas. The Netter ATEX vibrators are summarized in the following table.
