We have a wide range of accessories available for our blowers. You can view these by category below.

Unloading valves
Unloading valves Allows the machine to come up to full speed before they slowly close and apply the duty load. This limits the starting current as the electric motor accelerates up to speed and can help to reduce electricity costs where the tariff is “Maximum demand”. They are also available as a combination unloading/pressure relief set up with a range of sizes to suit most applications.
Pressure/vacuum relief valves
Pressure/vacuum relief valves Necessary in order to protect the blower/exhauster in the event of an obstruction or system failure which could lead to the machine overheating and seizing. They must only be used as a safety device and never as a means of controlling flow volume as part of a process. Hadron Engineering offer a full range of valves to cover most blower/exhauster duties.
Non return valves
Non return valves Fitted at the blower outlet as a precaution against product (solid or liquid) from regressing into the blower casing should there be a line blockage. They also serve to prevent a unit from motoring in reverse where two or more machines discharge into a common manifold and one unit is off-line. They are available in a range of designs (Duo-check & Mono-flap), materials and seals to suit any particular application. The Duo-check type is fitted with low torque springs in order to limit pressure drop.

Connections / Connectors

Flexible Pipe Connections
Flexible Pipe Connections The Hadron Engineering Ltd standard flexible connection is constructed of 3 ply silicon hose to withstand high temperatures and isolate against vibration. They come complete with bolt clamp fixings. Non- standard lengths are available on request.


Adjustable Switches
Adjustable Switches Pressure, vacuum and temperature control switches which are adjustable to suit the individual duty and provide vital protection for the blower/exhauster and electric motor.


Acoustic Enclosures
Acoustic Enclosures Noise levels are increasingly coming under scrutiny as part of the ongoing environmental clean up around the world. Hadron Engineering’s acoustic enclosures are designed to deal with this issue and standard designs are available to reduce the noise levels emanating from the package by up to 25 dBA at 1 meter. They have a galvanised finish and are suitable for outdoor installation. Air circulation within the enclosure is taken care of by a high volume ventilation fan via built-in attenuating ducting. Special requirements for even lower noise levels can be accommodated by employing our high efficiency design. We have standard designs to fit our own range of blower/exhauster packages but are often called upon to design and supply specials for other applications.


Inlet filter silencers
Inlet filter silencers Inlet filter silencers are combination reactive/absorptive employing the latest tubular reactive technology and utilising the filter element to double up as an absorptive muffler – the tubes are positioned to maximise attenuation and airflow while minimising pressure drop. They are constructed in durable carbon steel with a baked enamel finish.
Discharge silencers
Discharge silencers Hadron can provide bespoke silencers for all of your requirements, both reactive, absorptive and combination reactive/absorptive types. The silencers are designed and tuned to your actual application thus ensuring maximum sound attenuation. Special heavy duty designs are available for variable speed (inverter drive) duties where certain speeds can lead to amplified vibration levels. The minimum thickness for shell and heads is 5mm. Carbon steel construction is used for standard duties. In pressure applications, silencers can be designed to pressure vessel codes such as BS5500 and ASME VIII. Construction can also be in stainless steel or other specified material.


Inlet Filters
Inlet Filters We offer an extensive range of high quality inlet filters & inlet vacuum filters for extreme dusty environments. The standard range of polyester elements give 99%+ removal efficiency down to 5 microns whilst the paper elements achieve 99%+ removal efficiency down to 2 microns.


Pressure/Vacuum gauges
Pressure/Vacuum gauges A range of pressure and vacuum gauges filled with glycerine to damp out pressure pulsations. The standard is a back mounted 4” gauge but other sizes and mounting arrangements can be accommodated. They will normally be dual graduated in metric (Bar/MilliBar) and imperial units (psi) but other scales are available on request. Combination pressure/vacuum gauges can also be supplied.


Anti vibration mountings
Anti vibration mountings Mounting pads to isolate machinery from its’ supporting structure in order to prevent the transmission of vibration which, if unchecked, can be detrimental to bearings and machine components as well as adding to noise levels.
