| High Light | Agricultural Sprayer Tanks Breathable Vent ,High Airflow EPTFE Vent ,HDPE Waterproof Breather Vent | ||
The D17 high airflow breathable vent is the optimal pressure management solution for agricultural sprayer tanks, nurse tanks, and large drums used in modern farming operations. Its 17mm HDPE body and high-capacity ePTFE membrane are engineered to handle the intense breathing demands of rapid tank filling from bulk storage, high-volume spraying pumps, and the extreme temperature swings of outdoor agricultural environments. This vent guarantees that sprayer tanks remain structurally sound, free from vacuum collapse or pressure ballooning, while completely blocking dust, rain, pesticide residue, and liquid fertilizer from entering or escaping. Designed for the rugged reality of farm use, it provides season-after-season reliability with zero maintenance.
Agricultural sprayer tanks and drums endure some of the harshest operating conditions. Tanks are filled quickly from high-flow pumps, often from hydrants or nurse trucks, generating immediate positive pressure that must be relieved. During spraying, powerful PTO-driven pumps can empty a 1000L tank in minutes, creating a vacuum that can implode an insufficiently vented tank. These tanks sit outdoors, exposed to full sun, dust storms, and heavy rain. Non-breathable tanks develop pressure locks that disrupt sprayer calibration and flow consistency. Inferior vents can become clogged with dust, chemical crusts, or insects, or worse, allow rainwater in, diluting expensive chemical mixtures and potentially causing environmental contamination if overflow occurs.
The D17 vent is built for this environment. Its high airflow membrane, capable of moving over 2000 ml/min at minimal pressure drop, instantly compensates for rapid filling and emptying. The robust HDPE body is UV-stabilized to withstand years of solar exposure and is thick-walled to resist impact damage from tools, branches, or rough handling. The ePTFE membrane is dust-proof and waterproof, ensuring that no rain or field debris enters the tank, and no liquid chemical weeps out when the sprayer traverses steep terrain. By maintaining near-ambient tank pressure, it ensures consistent sprayer pump performance and accurate chemical metering, while protecting the tank structure from fatigue.

During rapid tank filling, air displaced by the incoming liquid is forced out through the D17 vent’s high-porosity ePTFE membrane at a rate matched to the fill pump, preventing tank pressurization. When the sprayer pump extracts liquid, ambient air is simultaneously drawn through the membrane into the tank, replacing the liquid volume and preventing a vacuum. The membrane’s dirt-shedding outer surface prevents dust and crop debris from adhering and restricting airflow. Its waterproof property means that even during a heavy downpour or when the tank is tipped, no external water enters and no internal chemical escapes.
Determine your maximum fill and spray rates: select a vent whose airflow rating exceeds the highest pump rate in your system.
Measure the available port size: many sprayer tanks have standardized threaded ports. We offer threaded D17 adaptors to fit common tank bung sizes.
Consider the tank’s agitation system: sprayers with vigorous hydraulic or jet agitation increase internal pressure and demand higher airflow.
Evaluate chemical exposure: test the vent with your specific tank mix, including adjuvants and surfactants, to confirm membrane compatibility.
Q: Can this vent handle the foaming that occurs with some tank-mix adjuvants?
A: The oleophobic ePTFE membrane resists foam penetration. However, severe foam could temporarily reduce airflow. We recommend an internal splash guard for foam-prone mixtures.
Q: Will the vent get clogged by dust while driving on unpaved farm roads?
A: The membrane’s smooth, non-stick surface and dust-repellent properties prevent dust accumulation. In extremely dusty conditions, an external shield may be added.
Q: Can I weld this vent into a rotationally molded sprayer tank?
A: Yes, rotomolded HDPE tanks are ideal. The welding surface must be flat and clean. We provide welding guidelines for rotomolded part surfaces.
Q: Does the vent affect the sprayer’s pressure regulator performance?
A: No, it stabilizes tank pressure, which actually helps the pump and pressure regulator maintain a consistent flow without fighting against vacuum or overpressure.
Q: Is this vent compatible with aerial application loading systems?
A: Yes, the high airflow capacity meets the demands of rapid loading for agricultural aircraft, ensuring fast cycle times without tank stress.
