General Aire 35-14 Replacement Steam Cylinder (SKU 7524) for RS25/RS25LC/DS25/DS35/RS35/DS20A/RS20A
A replacement steam cylinder used in compatible General Aire steam humidifiers to maintain normal steam generation performance as a routine service part.
Must only be used where the manufacturer specifies this exact part number/cylinder designation: 35-14 (SKU 7524)
Installation & Operation Notes:
Installation should be performed by a qualified HVAC technician (steam humidifiers are electrical/plumbing devices and often integrated into ductwork).
Follow the humidifier's service/installation manual for the specific model listed above.
Customer feedback notes the cylinder is a routine replacement item; one reviewer states their service technician recommended replacing it themselves to reduce service cost.
Maintenance & Troubleshooting:
Reviews repeatedly describe this cylinder as routine maintenance for a steam-generated humidifier and note it may need to be replaced yearly (user-reported maintenance interval).
If humidifier performance is inconsistent after replacement, the sources don't provide diagnostics; use the unit's service documentation to verify correct cylinder selection (including conductivity type), proper installation, and system setup.
User Reviews & Q&A Summary:
Reviews are very positive overall and commonly describe it as the exact replacement, working well and being a dependable recurring purchase.
Common themes include fast shipping, good pricing versus local contractor markup, and successful DIY replacement after a technician recommendation.
One reviewer notes manufacturer instructions assumed professional knowledge and felt vague, but still reported the unit worked great after installation.
Q&A highlights one common selection question: this 35-14 cylinder is confirmed as normal conductivity (not low conductivity).

Customer service was excellent
Supply House was great, however the manufacturer assumed I was a pro and so some of the instructions were vague. But the product is in and is working great.

good price/fast delivery
my HAC service guy recommended I replace the filter myself, since he did not have one with him. This saved me lots of money buying filter myself and installing it. I ordered the filter from supplyhouse at a significant savings and it arrived very quickly. Thanks.

Perfect Replacement
This was just what I needed at a fraction of the price that my local contractor was charging for the exact same product. SupplyHouse has very fast shipping too. Unit arrived two days after I ordered.

Good product at a great price and quick shipping
This is for NORMAL conductivity. It's my fault that I didn't check this, but it sure would've been nice if this important spec had been mentioned in the title for this version of the cylinder. It's in the title for the low conductivity version of the cylinder: "35-15 Low Conductivity Replacement Steam Cylinder for DS35/RS35 Humidifier."
