2.3 COOLING AND VENTILATING AIR

NOTE:

It is absolutely essential that an adequate flow of air for cooling, ventilating and engine combustion be supplied to the generator set. Without sufficient airflow, the engine/generator quickly overheats. Such overheating can cause serious operating difficulties and also may cause fire and personal injury. The installer must make sure that sufficient air is avail- able to the generator for cooling, ventilating and combustion. The installer also must provide for a path for exhausting the cooling air to the exterior of a compartment, if so equipped.

DANGER

Never use discharged cooling air for heating or permit such air to enter the vehicle interior. This air contains deadly carbon monoxide gas and other poisonous, flammable or explosive gases.

‹2.3.1 GENERATOR AIRFLOW

Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the top of the generator (Figure 2.9). This airflow cools the engine/generator and electronic components. The second part of the cooling system, a suction fan, draws air that is heated from a hot engine into a col- lector pan at the base of the unit. This heated air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.

Screening, louvers or expanded metal that cover air openings restrict airflow. Compensate for this by making the actual air opening proportionately larger. See the "Compensating for Restrictions" sec- tion.

NOTE:

Be sure to meet the minimum clearances illus- trated in Figure 2.4.

When the unit is installed on a suspended mounting system, one of several different methods of supplying airflow may be used as follows:

‹2.3.2 COOLING AIR INLET OPENINGS

The minimum size of the air inlet opening, whether the generator is housed in a conventional compart- ment or not, is at least 100 square inches (see Figure 2.10). This rule applies whether inlet air is brought in through an opening in the compartment door, an opening in the vehicle skirt, through duct- work, or by any other means.

•Using ductwork (Figure 2.12). The installer must be sure air is available to the top of the generator since air inlets are located at the top.

•By providing an opening in the vehicle skirt and space behind the generator for cooling airflow (Figure 2.13). Recommended clearance behind the back of the generator is at least 1/2 inch (13 mm).

02010-2, 04164-3 specifications

Guardian Technologies has made a significant impact in the air purification industry with its range of innovative products, particularly the models 02010-2 and 04164-3. These air purifiers are designed to enhance indoor air quality by leveraging advanced technologies, making them popular choices for both home and office environments.

The Guardian Technologies 02010-2 is an impressive model known for its portable design and effective purification capabilities. It features a 3-in-1 air cleaning system that includes a HEPA filter, a charcoal filter, and a UV-C light. The HEPA filter is essential for capturing allergens such as pollen, dust mites, and pet dander, making it ideal for allergy sufferers. The charcoal filter helps eliminate odors, capturing smoke and volatile organic compounds, while the UV-C light helps reduce germs and bacteria, ensuring a cleaner atmosphere.

This model is compact, allowing it to fit seamlessly into small spaces, while still providing powerful purification performance. With a whisper-quiet operation, it can be used in bedrooms or workspaces without causing disruption. Additionally, it features an adjustable fan speed, enabling users to customize the airflow according to their preference, along with an energy-efficient design that helps reduce power consumption.

On the other hand, the Guardian Technologies 04164-3 introduces a more advanced air purification system with similar foundational features but enhances the user experience with added functionalities. This model typically incorporates a combination of a HEPA filter and a UV-C light as well, but it often boasts smart capabilities. These may include an air quality sensor that helps monitor particulate levels in real-time, automatically adjusting the purification level when needed. This intelligent feature ensures that the air quality remains at optimal levels without requiring constant manual adjustments.

Both models prioritize user convenience, sporting features like filter replacement indicators, ensuring timely maintenance of the purification system. They are designed for ease of use and portability, allowing consumers to move them effortlessly from room to room.

In summary, Guardian Technologies’ models 02010-2 and 04164-3 stand out in the air purifier market due to their advanced filtration systems, ease of use, and smart technologies. These air purifiers are key investments for anyone looking to improve their indoor air quality effectively.
