Flex-Kleen ® SmartTimer II 

From the Leader in Baghouse Control Technology – 

The Next Generation SmartTimer Brings You 

Higher Levels of Performance, Versatility and Value

Flex-Kleen’s SmartTimer II Sets a New 

Standard for Pulse-Jet Dust Collector 

System Control and Communications 

Today’s plant operations require higher levels of efficiency and reliability at even lower costs. 

The SmartTimer II will help you achieve these goals. From the industry leader known for 

providing innovation in baghouse control technology, the SmartTimer II has been designed 

and engineered to bring you outstanding programming flexibility, higher levels of control, the 

ability to handle larger collectors, extended data logging and the capability to consolidate 

multiple control devices into a single cost-effective package. 

The SmartTimer II is less costly than complex PLC’s with similar control capability. Features include: 

• Three cleaning modes: continuous operation, demand 

pulse, and self-adjusting 

• Compact, integrated alternative to separate pressure 

switch/timer assemblies 

• Remote monitoring and adjusting of dust collector 

operating conditions 

• Up to fifteen auxiliary alarms to monitor high hopper 

levels, broken bag detection, zero speed switch, low 

air header pressure, high temperature sensor, etc. 

• Ability to identify a faulty solenoid valve even when 

there is more than one solenoid wired to a single output 

• Warning when the differential pressure level reaches 

pre-programmed safety set points 

• Warning when the pre-programmed low differential 

set point is no longer attainable 

• Modular wiring buss for easier wiring 

• Dual voltage input (120/240) 

• 20 output sequencer capable of pulsing up to 120 

solenoid valves 

• RS 232/485 serial communications ports which 

deliver the most cost effective remote monitoring plus 

control and interconnectability 

• Timers which can be connected in series with each 

timer uniquely addressable 

• 20 character alpha-numeric display to provide users 

with more concise and informative visual output in 

three languages (English, French or Spanish) and user 

selectable units of measure (English or metric) 

• Up to 365 days data logging capability with data 

resolution options 

• Discrete alarms programmable for each input (variable 

alarm output) 

• Optional program password protection 

• Sensor and alarm inputs utilizing a tri-color status 

indicator to provide visual display of inputs 

• 24 hour, 7-event programmable timer for maximum 

flexibility to provide adjustable controls to meet your 

changing conditions 

• Differential pressure transourcer with calibration feature 

to help support Title V – clean air act required 

• Built-in connection for J-type thermocouple to allow 

temperature measurement/logging if needed 

• Ability to be retrofitted to any manufacturer’s pulse-jet 

dust collector, including cartridge-type collectors 

SmartTimer II is the biggest advancement in pulse-jet control technology in the last decade.

up to 12 separate alarms for remote 

monitoring of dust collector auxiliaries 

(i.e., rotary valve, screw conveyor, compressed 

air pressure, Broken Bag 

Detector, high temperature sensor, etc.) 

• ADJUSTABLE PRESSURE ALARMS – 

provides alarm when pre-set safety 

pressure levels are reached or when 

low/off set point is unattainable 

• PROGRAM CLOCK/DATA LOGGER/7- 

EVENT TIMER – provides ability to 

retrieve historical data up to 365 days 

and gives user maximum flexibility to 

meet a variety of plant operating conditions

Important Notice to Users: Our timers are capable of use in a wide array of devices and in various applications. Any device or system incorporating a timer should be so designed 

that, in the event of failure, malfunction or normal wear-out of the timer, the system will become inoperative in a manner which will prevent property damage or bodily injury. 

CAUTION: 

1. Do not mount controls in high vibration areas without shock mounts. 

2. Do not mount controls in areas of high dust or corrosive atmospheres without a protective enclosure. 

3. Do not use a converter or inverter for the power source. 

4. Do not mount control in high transient voltage areas without an isolation transformer. 

5. Do not leave control box open. 

6. Do not allow a local repair shop to repair the controls, as we employ some very sophisticated components that could be further damaged. For service, call us directly at: 

800-621-0734. 

Flex-Kleen offers NEMA 4X-FPR enclosures with full view cover as a standard for mounting our controller. These enclosures are made of polyester and have a continuous hinge 

cover. The finish is gray. Other NEMA classified enclosures available. 

NOTE: In order to keep abreast of the latest technology, Flex-Kleen reserves the right to change components and/or design of controls without notice.
