The core precautions for the application of coarse air filters in livestock farms mainly focus on four dimensions: selection and compatibility, installation and sealing, maintenance and management, and environmental compatibility, to prevent impurity leakage, equipment wear and tear, and purification failure.
Selection and compatibility: Meet the scene requirements of livestock farms
Match the parameters of the ventilation system: Select filters based on the designed ventilation volume and wind speed of the breeding house to avoid a sudden increase in resistance due to air volume overload or insufficient air volume affecting the purification effect.
Priority environmental resistant materials: Select moisture-proof and corrosion-resistant filter materials (such as polyester fiber, nylon), which are suitable for the high humidity and slightly corrosive ammonia environment in livestock farms.
The filtration efficiency is suitable for the following scenarios: For brooding houses and farrowing houses, grades G3-G4 should be selected. For ordinary fattening houses, grades G2-G3 can be chosen. There is no need to pursue overly high efficiency to avoid energy waste.
Installation seal: Prevent air short circuit
Ensure proper installation: The gap between the filter and the frame should be less than 1mm. Sealing strips can be added to prevent dusty air from bypassing the filter element and directly entering the breeding house.
Follow the airflow direction: Install according to the “air inlet side” and “air outlet side” marked on the filter to avoid reverse installation which may reduce the filtration efficiency.
Clean the installation area: Before installation, remove the accumulated dust and debris from the ventilation ducts and the air inlets of the equipment to prevent secondary pollution.
Maintenance and management: Frequent and standardized
Fixed maintenance cycle: In dust-dense areas (such as breeding houses near feed processing areas), clean once every 1-2 months and replace within 3 months. The general area should be cleaned every 2 to 3 months and replaced every 6 months.
When maintaining, take proper precautions: Turn off the corresponding ventilator when cleaning or replacing, wear a mask to prevent dust from spreading into the breeding house or being inhaled by the human body.
Record maintenance ledger: Record installation time, cleaning frequency, replacement date, and adjust maintenance frequency in combination with the number of livestock and poultry in stock and seasons.
Environmental adaptation: Responding to the special conditions of livestock farms
Moisture-proof and anti-condensation: During the humid season (rainy season, plum rain season), a water deflector can be installed on the outside of the filter to prevent the filter material from getting damp, moldy and clogged.
Avoid pollution sources: The air inlet of the filter should be kept away from the area where manure and sewage accumulate and the feed crushing area to reduce the direct impact of large particles of impurities on the filter material.
Winter anti-freezing cracking: In cold northern regions, filter materials with good low-temperature toughness should be selected to prevent the filter materials from cracking due to low temperatures during ventilation in winter.
