| 1250 CFM, 2 HP, DUAL CARTRIDGE, AUTO PULSE DUST COLLECTOR |
This listing is for a new 1250 cfm, 2 HP, auto pulse, two (2) cartridge dust collector. The current list price on this unit is $3,500.00 USD. Discounts are available for approved distributors. This unit comes as pictured with a 55 gallon drum kit as standard equipment. This adds two feet to the overall height of the unit. In applications where headroom is limited, this unit can be used with an optional 5 gallon bucket kit. Without the barrel extension kit, the base unit sits directly on the floor, as pictured on the shipping skid. A bucket lid is substituted for the drum cover in these instances. Without the lift kit the list price is $3250.00 USD
The cartridge dust collector is an excellent choice to replace the common bag-house or dust bag type collector and can be used to collect almost any dry, fine dust particulate. The cartridge offers a large amount of cleaning filter material in a very compact area. Cartridge dust collectors take up much less space than bag house collectors and offer an impressive filtration efficiency of 99.7% against 1/2 micron particles allowing for in house venting in applications that do not produce noxious or poisonous gases.
It was designed with a 8 inch diameter, abrasive resistant, inlet to extend the filter life. The filters are cleaned individually with a reverse pulse of 90-125 psi compressed air. The reverse pulse is actuated with one of two, 1 inch solenoid valves located on the front of the unit via programmable sequential timer board. The auto pulse package is a 120v standard plug and go outlet unit. It can be used at any time to increase air flow during dust collector operation or after shut down. As factory programmed the unit will pulse one time every three minutes and advance to the next valve continuously. This unit is designed to deliver optimal performance when dust cake levels of 20-40-60 pounds are accumulated in between pulse cleaning intervals. It is equipped with an acoustical dampening package that will meet or exceed all noise level requirements per osha specifications.
The vertical placement of filters allow for the best possible release and removal of dust from the pleated filters with one reverse pulse. Each filter is cleaned individually on this unit. It has two 99.7 % efficient cartridges that contain 452 square feet of total cleaning surface area. Each 26 inch long and 12.75 inch diameter filter cartridge has pleats that are 2.375 inches deep. The center opening of the filter is 8 inches in diameter and is open on both ends before installation. Currently, it is offered with a 2 hp, (208v - 230v / 460v) 3 phase TEFC motor as standard equipment (7 - 6 / 3 amps). It is also available with a 2 hp, 230 volt - 11 amp, TEFC single phase input. The approximate dimension of this collector is 10 ft. high, 3 ft. wide and 3 ft. deep. It comes with a 55 gallon drum attachment as standard equipment or optional 5 gallon bucket attachment.
This unit can be equipped with our optional electrical package that includes the following:
- Soft motor starting: The amperage draw will not exceed the motor name plate rated amperes at any time. This reduces the initial cost of copper wiring because it is no longer necessary to consider the initial startup load. The initial startup requirements may exceed 5 times the rated name plate amperes when hard starting a variable torque application like high speed impellers. This requires over sizing of electrical wiring, fuses and breakers to prevent motor starvation and premature failure of electrical components on startup.
- On-Off Switch: Conveniently located on the dust collector, this is a push button start and stop control that engages the variable frequency drive. After the start command is triggered the motor will ramp to maximum velocity over ~ 20 seconds. When the stop command is received the unit will again decelerate over ~ 90 seconds and come to a complete stop.
- Thermal Motor Protection: The motor drive will constantly monitor the motor and the drive itself for any unusual spike in temperature throughout. If the temperature rises above acceptable parameters the drive will default and shutdown before any damage to the unit is sustained.
- Motor Fault and Report Monitoring: The motor drive is capable of displaying motor torque, hours of operation, actual amperage draw, percentage of motor capacity used, percentage of drive capacity used, the motor frequency in hertz, delivered line voltage and several other programmable LED display readouts. Factory settings are always in hertz frequency unless specified otherwise.
- Automatic Load Compensation Controls: The motor drive is programmed to compensate for changing load conditions. These conditions include but are not limited to extended length or reduced diameter of piping, blast gates and other restrictions in the air lines, atmospheric humidity, temperature and altitude adjustments, filter cartridge dust cake levels, and power supply brownout or over current conditions. Without this electrical package the motor will simply rotate at 60 hertz- 3450 rpm. If any one or more of the conditions listed above exist then the rated cfm of the unit will be reduced as a result. Then the only way to increase the cfm is to correct whatever condition(s) exist. But with this electrical package these conditions are corrected automatically through direct motor communication with the drive system. As a result, if the cfm should fall below rated levels, the motor drive will increase the motor speed to correct for this condition. The speed of the motor will continue to increase until 150% of the rated water column vacuum is achieved to restore air flow and maintain 100% load on the motor. The LED display will show this reading in real time with .1 hertz accuracy. This reading can also be used as a baseline to determine the most effective time to pulse the filters. We highly recommend the use of this system when possible. This can only be used when unit is placed inside as the controller has a Nema 1 electrical rating. For outdoor placement of the dust collector, the inverter drive must be relocated to inside the building.
Our VFD electrical package is included on this unit. Contact us with any questions you may have about your specific applications. This unit is generally in stock and ready for immediate shipment pending final electrical connections per customer specification.
Our equipment comes with a 1 year warranty against defect in workmanship or materials. We also offer an 85% return of the purchase price, excluding freight, for the return of the collector within 60 days after receipt of delivery if this unit fails to perform as described.
