Toilet Mobile Air Blower Installation

The installation of mobile air blowers in toilets should be comprehensively planned based on ventilation methods, the characteristics of natural and mechanical ventilation, and odor control requirements. The specific key points are as follows:

1. Ventilation Method Selection

Choose a natural ventilation, mechanical ventilation, or a combined approach based on the usage scenario. Natural ventilation relies on the temperature difference between the inside and outside of the toilet to create air convection, suitable for well-ventilated open areas. Mechanical ventilation uses fans to force air exchange, ideal for places with high foot traffic or enclosed environments (such as mobile toilets rented in scenic spots). It is recommended to prioritize a combination of natural and mechanical ventilation, which can reduce energy consumption while improving ventilation efficiency.

2. Key Points for Natural Ventilation Installation

1. Vent and Air Inlet Layout: The vent should be placed on the roof of the toilet, at a height of no less than 2.5 meters to prevent rainwater from flowing back in. The air inlet should be installed on the side, lower than the vent, to create an air convection channel.
2. Rain Protection Measures: Install rainproof louvers at the vent to prevent rainwater from entering while ensuring air circulation. For example, in areas like Ganzhou with heavy summer rainfall, special attention should be paid to rainproof design.

3. Mechanical Ventilation Installation Specifications

1. Exhaust Fan and Air Inlet Configuration:
   • It is recommended to choose a silent exhaust fan with a power of 10-15W, installed near the top center to ensure rapid air exhaust.
   • The air inlet should be equipped with a filter to prevent dust and odors from entering. The wiring should be waterproof to prevent short circuits.
2. Exhaust Vent Design:
   • The exhaust vent should be located away from areas where people are active to prevent odor diffusion. It is recommended to install it on the roof or high on the side wall (above 1.8 meters from the ground), avoiding direct sunlight and rain.
3. Ventilation Duct and Fan Selection:
   • The duct layout should follow the principle of being "short, straight, and smooth" to minimize bends and connections. For split-type toilets, the exhaust fan can be installed in an independent ventilation module, connected to the exhaust ports of each compartment via PVC ducts with a diameter of no less than 10 centimeters.
   • The fan power should be appropriately matched. For a single toilet compartment, a device with an air volume of 15-20 cubic meters per minute is sufficient. During installation, leave space for maintenance, level the fan body, and install rainproof louvers and insect screens.

4. Auxiliary Measures for Odor Control

1. Use activated carbon adsorption devices or deodorizing liquid sprays to form a double protection.
2. Design an "upward supply, downward exhaust" airflow pattern to accelerate the removal of stale air.
3. Regularly clean the exhaust vent filters to maintain ventilation effectiveness.
