FAHKNS Refrigerant Recovery Tank 30 Lb With 1/4 SAE Y-Valve

The FAHKNS 30 lb recovery tank features a dual Y-valve design. The red valve controls liquid outlet, while the blue valve handles the inlet, allowing precise regulation of gases and liquids. HP295 stainless steel provides strength with a powder-coated exterior for durability. This tank is suitable for a broad range of refrigerants found in household AC units and refrigerators. It’s best for technicians performing moderate-volume recovery in residential settings. A limitation is the absence of a float switch, which may require alternative level indicators in some workflows.
Mastercool 62010 30 lb Refrigerant Recovery Cylinder

The Mastercool 62010 is a 30 lb empty recovery cylinder made from HP295 steel with a yellow/gray powder-coated finish for corrosion resistance and long-term durability. It is compatible with all major refrigerants, including CFCs, HFCs, HCFCs, and blends such as R12, R22, R134a, and R410A. This product is best for professional shops needing a sturdy, reusable cylinder with broad refrigerant compatibility. It does not include refrigerant, so buyers should source refrigerant separately.
VEVOR 1 HP Refrigerant Recovery Machine

The VEVOR machine features a dual-cylinder configuration with a high recovery rate of up to 7.7 lb/min, significantly faster than single-cylinder models. It can recover both vapor and liquid refrigerants and includes a protective fan and condenser to manage heat. With a weight of about 30.9 lbs, it remains portable for service work. It supports a wide refrigerant range, including R134A, R22, R410A, and more. Best for technicians who need speed and reliability in mobile or shop environments. Note that it is a full recovery machine rather than a standalone tank, so it complements a subcooling workflow rather than replaces tanks entirely.
Flame King 50LB Refrigerant Recovery Cylinder

The Flame King 50LB cylinder is heavy-duty and designed for storage and transport of refrigerants. It carries DOT-4BA-400 specifications with AHRI guidelines, offering safety certifications for professional use. The dual Y-valve design enables separate control of liquid and vapor lines, and the steel body is powder-coated for durability. This option is best for larger service fleets needing robust, compliant storage. A potential limitation is its heavier weight, which may affect portability in tight spaces.
FAHKNS 30 Lb Reusable Recovery Tank Without Float Switch

This FAHKNS model uses HP295 stainless steel with a round neck design for easy grip. The dual valve system (red for liquid, blue for vapor) supports flexible operation in various recovery tasks. It includes brass vent valves for safety and a 1/4 SAE Y-valve for reliable connections. It’s best for installers who want a simple, durable tank for multiple refrigerants. A limitation is the absence of a float switch, which some technicians rely on for level indication.
Dollate 30LB Refrigerant Recovery Tank

The Dollate 30LB recovery tank supports R12, R22, R134A, R410A, and other refrigerants. It uses HP295 stainless steel with a high-gloss powder-coated exterior and a round base for stability. The Y-valve design with brass components allows precise control. It’s suitable for domestic HVAC tasks and small shops. A note: ensure compatibility with your existing recovery machine and hoses to maximize safety and efficiency.
Buying Guide
What to consider when choosing a subcooler-friendly refrigerant recovery setup
- Capacity and type: Choose a tank size (e.g., 30 lb, 50 lb) based on typical job scale. For frequent recovery, larger tanks reduce frequent empty/reload cycles.
- Valve design: A dual Y-valve setup helps separate liquid and vapor lines, improving safety and control during recovery.
- Material and finish: HP295 stainless steel or steel with powder coating offers durability and corrosion resistance in shop environments.
- Portability vs. capacity: Heavier tanks provide more capacity but are harder to move. If you travel between sites, lighter or dual-machine setups may be better.
- Float switch availability: Some tanks omit float switches. If level indication matters for your workflow, factor this in or plan for external monitoring.
- Compatibility: Ensure the tank and recovery machine support common refrigerants (R12, R22, R134A, R410A, etc.) and your local regulatory requirements.
- Safety features: Look for safety valves, pressure ratings, and certified construction (DOT/TC) when relevant to compliance and safety.
FAQ
- What is a subcooler in refrigerant recovery? A subcooler in this context typically refers to equipment setups that improve condensation and liquid recovery efficiency by cooling gas/vapor during recovery. Many units incorporate components that support subcooling concepts, though the core products here are tanks and recovery machines.
- Which tank is best for a small HVAC shop? A mid-size, dual Y-valve tank like the FAHKNS 30 Lb model offers reliable control for liquids and vapors without requiring specialized equipment.
- Do I need a float switch? Float switches help monitor liquid level inside tanks. If your process requires automatic shutoffs or precise level monitoring, choose a tank with a float switch or add external monitoring.
- Can these tanks handle all refrigerants? Most listed options are compatible with common CFCs, HCFCs, HFCs, and blends. Always verify compatibility with your service requirements and regulations.
- Is portability a concern? For mobile work, lighter dual-machines like the VEVOR unit paired with a small tank can optimize workflow, while heavier tanks suit fixed-shop setups.
- Are these products certified? Some models carry DOT/TC or industry-standard compliance; check the product page for certification details relevant to your region.
