Product Detail
Booth Refresher (Sludge Collection System)
Automating the collection process reduces the maintenance workload.
Applications
- Sludge Collection
Features
- Automating the work of treating the sludge in the booth water tank, which is conventionally done manually, reduces the number of times you need to clean sludge as well as the maintenance workload.
- Since water content of collected sludge becomes extremely low, the amount of waste is reduced to about one-third of the conventional amount, making it easier to store and dispose of sludge.
- The system is of the security-oriented explosion-proof type. The pump model appropriate for the spray booth can be selected.
- The water in the booth becomes cleaner, resulting in less sludge odor. Also, the water needs to be replaced much less frequently.
- The system features a space-saving design and can be used with most wet-type booths.
- Installing the collection square (option) in the water tank enables effective collection of floating dispersed sludge.
Configuration
- The floating dispersant treatment agent SK-410 that makes sludge incohesive and promotes gelation is put in the system.
- The floating dispersed sludge in the water tank is sucked and transferred by the pump.
- The centrifugal separator separates sludge from water and returns the purified water to the spray booth.

Automatic Water Supply System
Saves labor in water level management.
Applications
- Water level adjustment for a coating booth
Features
- Saves labor in water level management.
- A constant water level keeps the booth performance good.
- Can be attached to various types of coating booth.
- No auxiliary water tank is needed, resulting in space savings.
- The water supply valve is opened or shut as the upper or lower water level limit is detected.
Power Supply | AC200V |
Electric Specs | Normal |
Air Pressure | 0.4 to 1 MPa |
Air Consumption | 5 L/min or less |
Air-Type Automatic Water Supply System
When a small amount of air is pushed out as air bubbles from the detection pipe inserted into the water, a push-out pressure is needed that changes in proportion to the water level (insertion depth). The system detects this pressure (back pressure) with a high sensitivity sensor and operates an air pressure valve for water supply according to the water level so as to keep the water level inside the coating booth within a certain range.

Sock Air Balance System
This air balance system uses a tubular (sock-shaped) cloth filter to realize a quiet and clean nearly natural environment.
Applications
- Ventilation for the coating site
Features
This air balance system uses a tubular (sock-shaped) cloth filter to realize a quiet and clean nearly natural environment.
It realizes a comfortable, clean coating environment that is free from blowout air flow and temperature irregularity seen with the conventional air supply system.
Air Balance System

- Impact on the paint surface such as surface drying due to wind
- Dust thrown up by wind
- Painter feeling cold from wind
- Large chamber needed
- Burdensome task of filter replacement

Sock Air Balance System

A flow of evenly gentle air blowing at 0.1 m/s or less is blown out from across the filter, realizing a calm space.
- No impact on the paint surface such as surface drying due to wind
- Little dust thrown up by wind
- No spray mist caught in a turbulent flow
- Painter not exposed to wind (improved working environment)
- Filter easy to detach (It can be washed with water up to 10 times.)
- Appropriate special flame-retardant strings (polypropylene) used
Installation Example

Coating Booth

Coating Kitchen, Pump Room, Outer Booth

Cautions
- The sock filter is basically equivalent to a cloth air supply duct. It is effective in filtering large-diameter floating fine particles. To collect floating fine particles whose diameter is 10 m or less, however, an air handling unit or other device is required for filtering.
- The sock diameter, length, and other dimensions need to be selected based on the flow rate of supply air.
- When an ultraviolet germicidal lamp is used, make sure the sock filter is not directly exposed to the light of the lamp.
* We will be happy to design and install a sock air balance system for you. Feel free to contact our sales rep.
Booth Treatment Agent
To prevent the paint collected by the booth from adhering to the booth interior (make the paint incohesive), the agent aggregates sludge to make it easy to remove.

Caution on Bubble Release
When fast drying, powder, or soluble paint is used, water may overflow from the water tank as it releases bubbles. This causes a phenomenon such as ripples, eliminator clogging, or rising water level, resulting in degraded performance. Suppress bubble release by removing sludge frequently or using an antifoam agent.
About pH Control
The treatment agent makes water alkaline to slow the corrosion process of the water tank and other components. However, if the acidity of the paint used is high, it cannot be neutralized with the treatment agent alone. In that case, an alkaline agent needs to be used separately.
Usage Method (SK-410)
Initial Use
The following table shows the amount of agent to be used for the first time or after water has been replaced.
Situation | Water Condition | Usage Amount | pH Adjustment |
---|---|---|---|
New booth or after water replacement | Clean water | 0.03% of the water amount (for every ton of water → 0.3 kg) | Not necessary * 3 |
After treatment agent change | Sludge is remaining. The previous treatment agent is remaining. | 0.1% to 0.3% of the water amount * 2 (for every ton of water → 1 kg to 3 kg) |
* 2 Put the treatment agent little by little while checking the sludge condition and bubble release condition. In the case of a soluble paint, putting a large amount of agent (about 1 kg) at once can have an aggregation effect. Since this powerful aggregation effect generates a large amount of sludge, care needs to be taken about the filtering net becoming clogged.
* 3 Basically, pH adjustment is not necessary. However, if the acidity of the paint used is pH7 or less, or if the acidity of the booth water is pH7 or less due to the previously used treatment agent remaining, adjust the pH level to prevent the corrosion of the booth, by adding a commercially available sodium hydroxide solution (pH adjustment agent) little by little while paying attention to bubble release.
Daily Use
The following table describes the items of daily management. The basic information is provided here; make necessary adjustments based on the sludge condition.
- Put the treatment agent in installments (morning and noon) for effectively making the paint incohesive.
- Put a large amount of agent at the end of work (evening) for easy sludge collection.
Item | Description |
Usage Amount | Put an amount of agent equivalent to 1 to 3% of the amount of paint used in installments as shown below. * 4 |
Usage Method | Divide the amount of agent to be put per day as follows. |
Morning: At the start of work: /td> 1/4 of the total amount Noon: After lunch break: 1/4 of the total amount Evening: At the end of work: 1/2 of the total amount |
|
pH Check | While pH adjustment is not necessary, the pH level needs to be checked. * 5 |
* 4 In the case of a soluble paint, putting a large amount of agent (about 1 kg) at once can have an aggregation effect. When you wish to separate and collect sludge without using the treatment agent daily, it is recommended to add a sufficient amount of Sludge Killer for the accumulated sludge at once. Since the powerful aggregation effect generates a large amount of sludge, care needs to be taken about the filtering net becoming clogged.
* 5 Basically, pH adjustment is not necessary. However, if a highly acid paint is used, adjust the pH level to prevent the corrosion of the booth, by adding a commercially available sodium hydroxide solution (pH adjustment agent).
