Designed specifically for lateral installation on dairy vats, beer fermenters, and large mixing vessels, the Aomite Sanitary Rectangular Manhole Cover (Side Manway) provides spacious, unhindered access for tank inspection and manual cleaning.
Manufactured from premium forged SS304 (1.4301) or SS316L (1.4404) stainless steel, this inward-opening/outward-opening access door ensures complete hygienic safety. The internal surface is ultra-smooth with a precision mirror polish of Ra 0.4µm - 0.8µm, preventing bacterial adhesion. Equipped with highly durable, food-grade gaskets (available in Silicone, EPDM, NBR, or FPM), it delivers a reliable seal under fluid head pressure. As a source manufacturer, we offer standard sizes (such as 530x430mm and 430x330mm) and fully customized height and frame dimensions to meet your specific engineering requirements.

|---|---|---|
| Rectangular Manhole Cover | Lower Side / Bottom of the tank. | Designed to fit the human shoulder profile perfectly. Ideal for personnel entry for manual scrubbing, maintenance, and removing solid waste (like spent grain) from the bottom of fermenters. |
| Round Manhole Cover | Top / Dome of the tank. | Used for adding ingredients, dry hopping, or visual inspection from above. Handles higher pressure distribution better. |
Silicone (Standard Food Grade)
Excellent for general dairy and beer applications. Handles high temperatures well but is not suitable for strong acids/alkalis.
EPDM
Highly recommended for CIP (Clean-In-Place) systems and hot water/steam sterilization applications due to its excellent chemical and heat resistance.
NBR
The best choice if your tank contains oils, fats, or dairy products with very high lipid content, as it prevents swelling and degradation.
FPM (Viton)
Used for extreme industrial or harsh chemical environments requiring maximum resistance to aggressive solvents and ultra-high temperatures.
