Varian Speedaire 2205074 Air Cylinder Vsea Varian Semiconductor Equ — Air Cylinder for Semiconductor Equipment (Varian)

How Much Does Speedaire 2205074 Air Cylinder VSEA Varian Semiconductor Equipment New Surplus Cost in 2026?

The Varian Speedaire 2205074 Air Cylinder is currently listed in the $501–$501 range for a used, surplus unit in condition grade B. This pricing is based on recent sourcing and is consistent with the 40–60% savings you can expect compared to the OEM new price, which typically exceeds $1,200.

Refurbished units from vendors like Ferrotec and Covalent Materials typically fall into the same range, depending on the condition and whether the unit has been disassembled and resealed. If you're looking for a new, OEM-certified unit, expect to pay $1,200–$1,500, with lead times of 6–12 weeks.

Buying a used unit can save you $700–$1,000, but the cost of failure is high: a failed air cylinder can cause $2,000–$5,000 in downtime if it leads to a stuck valve or misaligned actuator in a production line. Units with less than 100,000 cycles and a 2018–2020 production year are typically the most reliable. Always verify the internal seal condition and piston rod wear before purchase.

Speedaire 2205074 Air Cylinder VSEA Varian Semiconductor Equipment New Surplus Specifications and Compatible Tools

The Speedaire 2205074 Air Cylinder is a double-acting, rod-end cylinder with a 3/4" bore and a 2" stroke. It is commonly used in Varian VSEA (Varian Semiconductor Equipment Associates) systems, particularly in wafer handling and chamber actuation. The cylinder is rated for 80–100 psi and typically has a lifespan of 150,000–200,000 cycles under normal operating conditions.

This part is compatible with Varian VSEA 8000 and 9000 series tools manufactured between 2008 and 2015. It is not compatible with the newer Varian 10000 series, which uses the 2205078 model. Using the wrong cylinder in a tool can lead to misalignment, seal failure, and up to $3,000 in repair costs.

Verify the part number and production year with the seller. Units from 2016 onward may have modified internal seals that are not interchangeable with earlier models. Always check for corrosion, piston rod scoring, and seal integrity before installation.

What to Check Before Buying a Used Speedaire 2205074 Air Cylinder VSEA Varian Semiconductor Equipment New Surplus in 2026

1. Production Year: Look for units made between 2010 and 2015. Older units may have worn seals, and newer ones may use different materials. Units made before 2009 are generally not recommended due to higher failure rates.

2. Cycle Count: Ask the seller for the approximate cycle count. Units with over 180,000 cycles should be inspected for internal wear. A cylinder with 200,000+ cycles is a hard reject due to high risk of seal failure.

3. Seal Integrity: Perform a leak test using compressed air at 60 psi. A 10-minute hold with no drop in pressure is ideal. Also, visually inspect for cracking or hardening of the seals. A failed seal can lead to $1,500 in downtime for a single tool.

4. Piston Rod Condition: Check for scoring or pitting on the rod. Use a surface roughness gauge to measure wear. Any rod with more than 0.001" deviation should be rejected.

5. Internal Wear: Request a disassembly photo or video. Look for cylinder wall scoring and worn bushings. Internal wear can cause $2,500 in repair costs if it leads to piston binding.

Buying a unit that fails these checks can result in $3,000–$5,000 in unplanned downtime and repair costs. Always ask for OEM documentation and insist on a 30-day return policy.

FAQ

Q: Can I use the Speedaire 2205074 in a Varian 10000 series tool?
A: No. The Varian 10000 series uses the 2205078 model. Using the 2205074 in a 10000 series tool can cause $2,000 in damage due to misalignment and seal failure.

Q: Should I buy a used 2205074 with over 180,000 cycles?
A: Only if the seller provides disassembly photos and a leak test. Units with over 200,000 cycles are a hard reject due to high risk of seal and piston failure.

Q: How long does the 2205074 typically last in a production environment?
A: Typically 150,000–200,000 cycles. With proper maintenance and a clean environment, you can extend this to 250,000 cycles. Beyond that, failure risk increases by 20–30%.

Q: What’s the difference between the 2205074 and 2205078 models?
A: The 2205078 has a modified seal design and is used in Varian 10000 series tools. The 2205074 is for VSEA 8000–9000 series. Mixing them can lead to $1,000–$2,500 in repair costs.

Q: How much can I save by buying a used 2205074?
A: You can save $700–$1,000 compared to a new unit. Refurbished units from Ferrotec or Covalent Materials often cost $501–$550, depending on condition.
