Aaon P34340 Filter Drier

The Aaon P34340 Filter Drier is a high-performance 1/2 inch sweat sealed filter drier specifically engineered for commercial refrigerant liquid line applications. This OEM HVAC replacement part is essential for maintaining the integrity of AAON rooftop units and chillers by aggressively removing moisture, harmful acids, and physical debris from the cooling circuit. Constructing a system with this liquid line drier prevents the formation of ice crystals and internal corrosion, ensuring high-efficiency heat transfer and reducing the risk of compressor failure. Designed with a 1/2" sweat connection, it provides a secure, leak-free seal suitable for high-pressure commercial refrigeration parts environments. Its compact, corrosion-resistant steel shell is built to withstand the rigors of continuous industrial operation, making it the preferred choice for technicians performing routine preventative maintenance or emergency system repairs.

• Advanced Contaminant Filtration: Features a high-capacity molecular sieve and activated alumina to capture moisture and neutralize acids.
• OEM Precision: Direct replacement part (C-164-S) ensuring perfect fitment and performance in compatible AAON systems.
• Durable Construction: Robust epoxy-coated steel exterior provides superior resistance to corrosion and environmental wear.
• Optimized System Protection: Prevents thermal expansion valve (TXV) freeze-ups and protects high-cost compressors from debris damage.

What is the connection size for the Aaon P34340?
This model features 1/2" sweat connections, requiring professional brazing for a permanent, leak-proof installation in the liquid line.

Is the P34340 compatible with all AAON units?
While it fits many popular AAON models like the RQ series, compatibility depends on your specific model and serial number. Please verify your technical manual before installation.

Why is a sealed filter drier used instead of a replaceable core?
Sealed driers like the P34340 offer a more cost-effective and compact solution for medium-capacity systems where a complete swap is faster and more reliable than cleaning a reusable housing.
