Plural of Bellows
The noun “bellows” is plural in form. Cambridge treats it as a plural noun and uses “a pair of bellows”; Merriam-Webster explicitly allows singular or plural construction. Therefore, do not force one universal agreement rule. Use pair-of counting when that makes the number clear, and follow established construction in the sentence.
“Bellows” is plural in form. “A pair of bellows” is common for one device, and dictionaries record both singular and plural construction.

Quick tests
Plural-choice test
Do you need to make the number of devices explicit?
If yes: Use “a pair of bellows” for one and “pairs of bellows” for more than one.
If no: Keep “bellows” and follow the established agreement of the construction.
Caveat: The verb form “bellows” from “bellow” is a separate grammatical item.
Examples
A pair of bellows was kept beside the forge.
Pair-of wording makes one device explicit.
The bellows are stored near the furnace.
Plural construction is recorded and natural.

Agreement variation is part of the noun’s recorded behavior.
Further guidance
Core difference
Use “bellows” for the device; “a pair of bellows” clearly counts one.
Fast Test
When number matters, pair-of wording avoids ambiguity; otherwise preserve idiomatic singular or plural construction.
Usage Boundary
Do not assume every -s noun must take plural agreement here; authoritative dictionaries explicitly record variation.
