Filters Typ 482
Compressed air filters serve to remove impurities (condensation water, pipe scaling, rust particles) from the air in the working place. The cleansing is done in two stages by means of cycloning (condensation) and PE-Filter-elements (solid contamination). Three opportunities of drain valves are available: manually-operated-, semi-automatic- or fully-automatic (internal- or external) drain valves.
Micro-FilterS Typ 491
Microborosilicate air filters are suitable for use in all situations in which the required purity of the compressed air is especially high. As the second stage after the standard filter they remove almost without residue the smallest remaining particles of water, oil or dirt to 99,999% (for 0,01μm.).
Activated-Charcoal-Filters Typ 493
Active-charcoal filters serve to remove oil vapours and other organic pollutants from pressurised air. The active-charcoal fibre (the adsorption capacity of which is sufficient for approx. 1,000 hours of operation) is positioned between two stainless-steel nettings. The air at the inflow opening should be dry and free of particles; this is why the prior attachment of a micro-filter is categorically recommended.
Caution! Some hazardous substances are either not at all or only slightly adsorbent, therefore non-removable with active charcoal! Such substances are i.e., carbon dioxide, carbon monoxide, ammonia.
Filter Pressure Regulators Typ 480
Filter pressure regulators unique in space-saving model the functions of a filter and a regulator in one piece of equipment. (see single definitions)
Pressure Regulators Type 481
Pressure regulators (diaphragm type) of compact block design in two sizes. Facilities on both sides for flange mounting of further units. Panel mounting, direct mounting or bracket mounting on housing or cover. These units are, of course, fitted with a secondary exhaust (self-relieving) and are largely unaffected by fluctuations in primary pressure. Three pressure ranges are available, up to 6, 10 or 16 bar; regulators are also available without pressure gauges. Simple locking of setting by pressing in handwheel. Version available with keylockable handwheel. Pressure gauge can be mounted on either side. Important: Use of filter always recommended.
Battery regulator Typ 490
These kind of regulator are equipped with a continious pressure supply. The pressure inlet can be selected on left or right side, so that it can be used for a so called »battery mounting« .
The attached regulators are offering independent and different pressure adjustments because the supply pressure is existing on both sides of the unit. (Connection No. 1). The working pressure (secondary pressure) which is kept almost constant regardless of pressure fluctuations (inlet pressure) in the system and air consumption, is available on the backside connection (No. 2).
The regulator(diaphragm type ) is fitted with a secondary exhaust (self-relieving) to reduce the working pressure without air extraction. Contamination and damage could be avoided if a filter of the model 482 is instaled. We recommend to use the units port size G 3/8 as they have the higher flow capacity. Important: Use of filter always recommended.
Lubricators Typ 483
Lubricators add a fine oil fog to the compressed air, this effecting a constant and reliable lubrication of pneumatically controlled compressed air tools, valves and cylinders etc.. Refilling oil while under pressure is possible. Needle valve for oil adjustment with high drop constancy for long periods of time. Also available with metal sight dome.
Maintenance Units two-piece Typ 488 and 3-piece Typ 489
The number of possible variations which can be created by the simple block-mounting of individual units to form air treatment units is naturally countless. We have listed some of the most frequently-used versions below. As regards filters, there are options for the bowls and drain valves, while for filter regulators there is generally a pressure range of up to 10 bar; various reservoir options are available for the lubricators.
Ball Valves Typ 487
Ball valves with exhaust (3/2 directional control valves) for flange-mounting to variobloc- FRL´s are particularly suitable for use at the start of these as main shut-off valves. Actuation by 90° rotation of lever, marked clearly with switching position: Lever in transverse direction – Valve closed, outlet exhausted (narrower nominal size). Lever in lengthwise: Valve open, exhaust closed. Silencer to reduce exhaust noise.
Two sizes with port threads from G1/4 to G1. Direct mounting or bracket mounting on the housing is possible. Version with pneumatic gear ( onliy size II) enables the application in danger of explosion areas as remote control. The swing construction warrants a high starting linge moment andso a high forming energy (nessesary after long period of down time).
3/2-Way Starting Valves, electrical Type 485
3/2-way starting valves in modular design for flange-mounting to variobloc-maintenance units. Valve closed without current, with manual emergency-operation. Port sizes G 1/4 to G 3/8.
Distributors Type 486
Distributors with non-return valves are ideal for tapping off unlubricated compressed air when flange-mounted upstream of the lubricator. The non-return valve prevents oil from being taken in from the lubricator or lines. This does, however, mean that the system downstream of the non-return valve cannot readily be exhausted. Two sizes with four outlets and port threads from G1/4 to G1.
Pneumatic Starting Valve Type 484
Starting valves and filling valves in modular block design serve to raise the pressure gradually in pneumatic systems when they are being started, for example after emergency shut-off. When switched on, throttles release at first only a small orifice. Only when the pressure has reached about 60% of operating pressure is the full orifice opened. In the opposite direction (relieving) the full orifice is opened by means of a non-return valve. In combination with ewo-equipment such as the 3/2-way valve, ball valve or solenoid valve a complete on-and-off unit can be assembled. Port sizes G 1/4 to G 3/8.
