Air Intake Filters Protect Heavy-Duty Engines

Porvair air filters are designed for use in diesel engines used in off-road, agriculture, construction, fleet and marine automotive applications, to provide high air quality and long service life. According to Porvair, air intake filters are essential for optimum heavy-duty diesel engine performance. Air containing contaminants such as dust, smog, fumes and other microscopic particles can cause significant damage to all engine components and clogged air filters create increased fuel consumption, exhaust fumes and environmental pollution.

Porvair diesel air filters utilise a high-strength resin-impregnated cellulose pleated filter, claimed to combine good permeability with the necessary filtration efficiency to protect the engine combustion equipment. The gravimetric filtration efficiency is in excess of 99.95 per cent and is able to operate for many hundreds of hours without change under heavy dust load. In some cases, the filter units will retain more than 12kg of contaminant before change out is necessary.

Cleanable versions of the Porvair diesel engine filter cartridges are available for applications where the carrying of spares is not operationally possible. These can be cleaned using hydrocarbon solvents, such as fuels, or with steam. Air intake filter units are also available with cyclonic pre-separators, for use where the operational environment has a high concentration of dust. This is claimed to significantly increase the working life of the filter cartridges.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
