Smokeeter FAQs


To determine which Smokeeter is best for your space, we recommend answering the following questions, if additional assistance is required, call us or email us!


1. Does your space have strict aesthetic standards?
    If you answered yes, we suggest SE24, FS, or LS units (depending on space size).
    If you answered no, we suggest the SE40 or SE50 (depending on space size).
    If you're working in an industrial environment, we suggest the CC/DC.
2. Are you looking to install ducted, flush mount or box type units?
    If you answered ducted: FS or LS units (Please note: There will be additional installation costs for ducted units).
    If you answered flush mount SE24 units
    If you answered box type: SE40 or SE50 units
3. Is odor control a big concern?
    If odor control is a main concern, FS and LS units have a carbon module option to combat heavy odors.
4. What is the size of your space?
    If you're in a small office space, SE24 units are ideal.
    For mid-sized spaces, SE40 or FS units are suggested (depending on odor control).
    For larger spaces, we recommend SE50 or LS units (depending on odor control).
    Industrial-sized spaces are recommended to implement CC/DC units.

Use our CFM Calculator or find the number of units needed in a room based on the following equation:

Multiple the L x W x H of your space by the amount of air changes required per hour (generally 8-10) and then divide by 60. This number will equal to the amount of CFM that is required.

For example, if you're interested in the SE50 and your room requires 3000 CFM, we would suggest two units as they each offer 1500 CFM while running on high speed.

For assistance in determining how many units you are in need of, get in touch with us by calling (866) 651-9761 or emailing info@aircleaningspecialists.com or requesting a free quote.

Major cleaning is confined to the prefilter, ionizer, collection cell and the inside cabinet. These should be cleaned periodically to ensure continued efficiency. Cleaning may be required from once a month to once every four months depending on the air quality. Before cleaning your Smokeeter, components must be removed.

NOTE: The carbon filter cannot be cleaned and needs to be replaced as required.

How to Remove Components

1. Turn off the unit
2. Open the access door
*For added safety, manually discharge the ionizer and collection cell/unicell in the following manner. Place the blade of a common screwdriver (with insulated handle) across the ionizer wire support and then the ionizer frame. Next, place the screwdriver blade across the cell end plate and then across a cell “hot” plate. This will remove any residual charge that may not have bled off.
3. Slide components from the cabinet.

How to Clean Smokeeters

1. Disconnect power to unit and remove components.
2. The ionizer, collection cell/unicell, and prefilter can be cleaned by soaking in a hot solution of Smokeeter brand detergent for 30 to 60 minutes. If possible, agitate the solution to aid in dirt removal. If agitation is not possible, soaking time should be increased.

CAUTION: Do not use temperatures exceeding 160˚F and do not steam clean at this may cause permanent damage to the components. If detergent other than Smokeeter brand is used, care must be taken to ensure that it contains an aluminum inhibitor so that it does not attack the aluminum components.

3. Remove the components from the detergent bath and immediately flush away any residue and rinse thoroughly with clear hot (less 160˚F) water. Shake off excess water and let components dry for 30 to 60 minutes. Set the cell so that its plates are in a vertical position for drainage.
4. Vacuum clean the interior of the cabinet and clean off all electrical connections before reinstalling the components.
5. Reinstall the components into the cabinet. 6. Apply power to the unit and confirm indicator light is illuminated.


1. Turn unit off, open faceplate grille and wait 15 seconds for high voltage charge on unicell to bleed off.
* For added safety, manually discharge the unicell by placing the blade of a common screwdriver (with insulated handle) across the ionizer wire and cabinet ground as well as one of the charged cell plates to cabinet ground.
2. The unicell and prefilter can be cleaned by soaking in a hot solution of Smokeeter brand detergent for about 30 minutes.

CAUTION: Do not use temperatures exceeding 160°F and do not steam clean as this may cause permanent damage to the unicell. If detergent other than Smokeeter is used, care must be taken to assure that it contains an aluminum inhibitor so that it does not attack the aluminum components.

3. Remove the components from the detergent bath and immediately flush away any residue. Rinse thoroughly with hot water. Shake off excess water and let components dry for 30-60 minutes. Set the unicell so that its plates are in a vertical position for drainage. Do not reinstall the unicell until it is thoroughly dry.
4. Vacuum the interior of the cabinet to remove any loose lint or dust that may have accumulated.
5. Clean the faceplate grille by wiping down with a lintfree, soft cloth and a suitable household cleaner.
6. Reinstall or replace the after-filter.
7. Reinstall the unicell with prefilter, making sure the high voltage plug-in connectors are securely connected to the unicell.
8. Secure faceplate grill and turn unit on.
* If the indicator lamp flickers or does not come on at all, the unicell assembly was not thoroughly dry. Air passing through the unit will dry out the unicell and the lamp will eventually turn on.


Normal maintenance is confined to periodic cleaning of the cell, ionizer, and filters, plus checking of the drive belt. Rarely is any other maintenance necessary.

A. Cleaning Instructions

Turn unit off and depress both push-to-test buttons to remove any residual charge from components.
Slide dirty collection components (prefilter, ionizer, cell and after-filter) from cabinet.
While there are many methods of cleaning, certain key cleaning criteria contribute to the effectiveness of every method. These include the type of detergent, detergent strength, water temperature, agitation/impingement, duration, rinse procedure and dry-out time.

Type of Detergent

In general, the detergent used in most applications will be alkaline in nature. It is extremely important that the detergent have a built-in buffering agent to prevent deterioration to the aluminum. Detergents are available through United Air Specialists for specific applications and contaminants.

Detergent Strength

Detergent concentration, or “strength,” in a mixture with water varies with the application from 1:1 to 5:1 to even 20:1 parts water to parts detergent, refer to detergent manufacturer’s directions. More or less detergent may eventually be required for effective cleaning at reasonable detergent cost. Typically, 20:1 is recommended as a starting point. Experimentation is almost always necessary.


CAUTION: Never mix acid and alkaline detergent for manual cleaning. Detergent mixing could cause rapid heat release, gel formation or other undesirable conditions.


Water Temperature

Detergents can be up to twice as effective in hot water and hot water alone is very effective in softening builtup residue. Water temperature should be 140°F to 180°F, not to exceed 190°F.

Agitation/Impingement

These methods are virtually the same, with impingement being the most extreme form of agitation. Any liquid movement over built-up residue will dissolve some of the contaminants, allowing detergent to work on the next layer. A reduction in cleaning time duration usually results.

Cleaning Cycle Duration

In most cleaning methods, adequate time must be allowed for the detergent to dissolve the contaminant thoroughly. Reaction time will vary depending on detergent strength, temperature, and agitation. Guidelines for mixing, heating and expected results are included on specification sheets for most detergents.

Rinse Procedure

Cleaned components must be rinsed off quickly and thoroughly to remove any remaining contaminants. Even if the components appear to be clean, some detergent residue may remain. This should be removed because the residue may contribute to voltage bleed-down when the components are placed in service. Also, even though the detergent is “buffered” (i.e., treated to prevent deterioration of the aluminum), prolonged contact with the components could cause minor corrosion. As with cleaning, hot water should be used for rinsing.

Dry-Out Time

Collection components should be dry before the system is placed back into operation. Start-up of a wet system causes dead shorts and/or arcing conditions. Wet ionizers, collector cells and mesh filters should be placed in a warm room until they are dry. Techniques such as hand wiping insulators and blowing dry with compressed air will greatly shorten drying time.

B. Component Cleaning Methods

The manual cleaning method selected for a given system will depend on the type of contaminant, rate of deposit, facility limitations such as cleaning time windows (process down time) and available utilities. Any one of the following three acceptable cleaning methods may be included in such a plan.

Hot Detergent Soak Tank

This method involves placing components in an agitated solution of hot water and detergent, and is the most effective method. With proper detergent selection, this procedure will quickly remove most contaminants collected in a precipitator.
Components should not be placed in highly concentrated detergent solutions or allowed to soak for extended periods (e.g., overnight), especially at elevated temperatures. Extended soaking (e.g., days) in solvent or detergent solution will degrade components over time and should be avoided.

Automatic Parts Washers

Certain commercially-available units combine and automate the features necessary for effective cleaning, including water heating, detergent injection, agitation, rinsing and drying.

Portable Pressure Washer

A self-contained pressure washer with a spray wand can be an effective cleaning method, providing it is used with caution. Care must be taken not to expose collection cell plates to close-up and prolonged blasts of high temperature or high pressure water. Cell plates deform under continuous exposure to such conditions.

Wipe off contaminant from the high voltage insulators located on the back wall of the cabinet.

Reinstall components in the cabinet, close the door and turn the unit on. Connecting springs between cell and ionizer sections must be turned to the center of the cabinet for double component units (i.e., units with adjacent removable components — DCN). Electrical contact must be made between cells and ionizers by these springs. Make sure wall and door ground springs are in place and making contact with ionizer and cell endplates, respectively. See Figure 14 for properly aligned assembly.


HOW TO REMOVE COMPONENTS

1. Turn off the unit.
2. Open access door.
For added safety, manually discharge the unicell in the following manner: Place the blade of a common screwdriver (with insulated handle) across the ionizer wire and ionizer fin. Next, place the screwdriver blade between any two cell plates. This will remove any residual charge that may not have bled off.
3. Slide components from the cabinet.
