How to Start Using a Portable Thermal Fogger?
Charge the battery
Fully charge the battery before first use (approximately 1 hour)
Check the fogger liquid
Fill the tank with triethylene alcohol (glycol liquid), avoid overfilling
Locate the On/Off button
Identify the power button on the device
Proper grip technique
Hold with an ergonomic grip, index finger on the trigger
Prepare the testing area
Close doors and windows in the area you want to test
Turn on the machine
Activate the device by pressing the power button
Try short bursts
Initially generate fog in short 2-3 second bursts
Control fog direction
Point the device toward the area of interest (10-15 feet range)
Clean after use
Clean the nozzle after each use
Recharge the battery
Keep spare batteries ready if extended use is required.
How to fill and prepare the fogger for use?
To prepare your portable fogger, first ensure the device is turned off and the battery is fully charged (approximately 1 hour charging time). Locate the liquid reservoir and carefully fill it with triethylene glycol (glycol liquid) to the recommended level—avoid overfilling as this may cause clogging or improper performance.
After securing the reservoir cap tightly, check that the nozzle is clean and unobstructed. Insert the charged battery until it clicks into place, then allow the device to sit upright for 1-2 minutes to let the liquid properly saturate the heating element.
Before actual use, test the fogger by pointing it in a safe direction and activating it in short 2-3 second bursts until you observe consistent, paper-white fog emission. Always maintain a proper grip with your index finger positioned comfortably on the trigger for controlled operation.
What safety precautions should be taken?
| Category | Safety Precautions |
|---|---|
| Personal Safety | • Avoid directly inhaling the fog • Prevent direct contact with the eyes • Wear rubber gloves to protect yourself from chemicals • Wear long-sleeved clothing • Use safety goggles |
| Chemical Handling | • Avoid direct skin contact with triethylene alcohol • Use a funnel when refilling • Read chemical specifications and safety data sheet • Keep chemicals away from children's reach • Clean spills immediately |
| Device Operation | • Ensure proper ventilation in closed spaces • Don't operate the device continuously for more than 30 seconds • Take 1-2 minute breaks between operations • Avoid use near electrical equipment • Don't use near flammable materials |
| Storage & Maintenance | • Remove the battery before storage • Keep away from heat sources • Drain liquid before long-term storage • Clean the nozzle regularly • Follow the manufacturer's maintenance guidelines |
| Emergency Response | • Move to fresh air if the chemical is inhaled • Rinse immediately with water if skin contact occurs • Use a CO2 extinguisher in case of fire • Keep emergency contact numbers accessible • Have a first aid kit nearby |
What is the Capacity of a Portable Fogger?
Liquid Reservoir Capacity
Most handheld portable foggers like the Applied Physics model have relatively small liquid reservoirs, typically ranging from 100- 300 mL of fluid capacity. This allows for a balance between portability and operational duration.
Runtime Capacity
The device can typically operate for 5-15 minutes of total fogging time on a single fill, depending on whether continuous or intermittent fogging is performed.
Range Capacity
According to the product information, the fog travels 10-15 feet, depending on airflow velocity, making it effective for localized testing in clean rooms.
Battery Capacity
The rechargeable lithium-ion battery provides approximately 30-60 minutes of intermittent operation before requiring a recharge, which takes about 1 hour to complete.
Output Capacity
These devices typically produce a moderate volume of visible fog, sufficient for visualizing airflow patterns in controlled environments but not designed for high-volume applications like theatrical or outdoor fogging.
Why the Portable Fogger Is Essential for Quality Control
- Documented: Capture evidence for compliance records
- Analyzed: Identify subtle airflow issues before they become problems
- Demonstrated: Train personnel on proper airflow patterns
- Verified: Confirm the effectiveness of corrective actions.
Advantages Over Alternative Methods
