RV Airflow Systems — RV Air Conditioner Airflow Module (Coleman Mach 3/10/15/Q)
Published · Researched 2026-09-21
2026 lineup note: As of September 2026 RV Airflow Systems (rvairflow.com, RPI Components, custom-made in the USA) remains current, sold per A/C model family — this dossier covers the Coleman Mach 3, 10, 15, Q variant (two variants: standard Coleman ceiling assembly with two filters, and new Coleman ceiling assembly with single 12×12 filter). Dometic variants exist as separate SKUs — buy for YOUR A/C model, not generically. Patent pending.
Version lineage (2023–2026)
- RV Airflow launch (circa 2020–2021): Styrofoam (EPS) plenum insert that captures 100% of the A/C's air and directs it into the ductwork, replacing the leaky stock air-distribution box. Forum buzz peaked 2021–2022 (jaycoowners.com threads).
- Model-specific SKUs: Coleman Mach 3/10/15/Q; Dometic Brisk II / Penguin II families (separate products).
- 2023–2026: No hardware revision documented; the product is a static EPS molding. The 2021-era "comeback15" 15%-off cart-abandonment code is long expired — don't expect it to work.
Overview
The RV Airflow is a $150-ish block of 3-lb expanded polystyrene that installs in the plenum — the dead space between your rooftop A/C and the interior ceiling assembly — and forces all the conditioned air into the ducts instead of letting it leak and recirculate inside the ceiling cavity. Owners report the two things that matter: more even temperatures front-to-back, and a noticeably quieter A/C (less turbulence, less dump-through-the-ceiling roar). It's the highest-satisfaction-per-dollar A/C mod in RV forums, with the caveat that fitment is model-specific — measure first.

Pricing
- MSRP / street: UNVERIFIED — rvairflow.com pricing is rendered via JavaScript and was not captured. Historical datapoint: a 2021 jaycoowners.com post reported 2 kits for $327.57 USD shipped DHL to Canada (~$150+/kit net of international shipping) — dated, not current. Re-verify live; community consensus centers around ~$150–180/kit.
- Note: one kit per A/C unit — dual-A/C rigs need two.
- All prices USD, research date 2026-09-20.
In the Box
- EPS plenum module (model-specific)
- (UNVERIFIED: install hardware, instructions, seal materials — confirm.)
Warranty

Support & Parts

Community Verdict
The RV Airflow is the rare RV mod with near-universal owner satisfaction: "bought 2 of these based on other folks w/ Jayco Class A's successfully installing them" is the typical purchase story (jaycoowners.com), and the post-install reports consistently cite quieter operation and more even cooling. The skeptics' case is honest too: it's a precisely-cut foam block at a premium price, some owners DIY equivalent baffles with foam board, and the performance claims (efficiency, energy savings) are manufacturer-claimed, not independently tested.
Additional voices (Sept 2026 research): the fitment conversation is the whole pre-purchase thread — "I sent my A/C dimensions to RV Airflow... 'Unfortunately, with a plenum of that depth I do not believe we have a kit that would be compatible'" (jaycoowners.com). Measure your plenum depth before ordering; some owners trim the plastic inserts for fit. The noise reduction is the most consistently confirmed benefit — even skeptics concede the A/C runs quieter. eBay knockoffs exist at ~$70 for two ("DUAL UNIT (2X) COLEMAN RV A/C Upgrade MODIFICATION KIT", 86 sold) — unbranded Styrofoam with no warranty and a Prop 65 warning; the community treats them as a gamble.
Long-term durability & warranty-claim reality
It's a static foam block — there's nothing to wear out. EPS is temperature/water resistant and mold-inhibiting per the manufacturer; the risk is physical damage during filter changes or a poor fit rattling. Realistic expectation: lasts the life of the A/C. The warranty question is worth one email since the price is premium for foam.
Version history — year by year
- 2023: Current; model-specific SKUs established.
- 2024: No revision documented.
- 2025: No revision documented.
- 2026: Still current; patent still pending per site.
Head-to-head vs closest rivals
- No direct catalog rival — this is the only A/C-airflow product in the catalog. The comparison set is behavioral:
- vs DIY foam-board baffle: free–$20, same principle, no precision fit, no support. RV Airflow if you want guaranteed fitment; DIY if you're handy and skeptical of the price.
- vs eBay unbranded kits: ~$35/unit vs. ~$165 — no fitment support, no warranty, Prop 65 styrene warning. A gamble, not a plan.
- Outside the catalog: KoolRV (the other branded A/C airflow director); upgrading to a higher-BTU or soft-start-equipped A/C (solves different problems — capacity vs. distribution).
Care & maintenance
None beyond normal filter changes — don't damage the module when removing the ceiling assembly. If it rattles, the fit needs shimming.
Buying traps
- Fitment first: measure your plenum depth and match the ceiling-assembly variant (two-filter vs. single 12×12) — wrong variant = expensive foam paperweight.
- One per A/C: dual-A/C rigs need two kits — budget accordingly.
- The expired coupon: "comeback15" is a 2021 artifact — don't plan the purchase around it.
- Knockoffs: unbranded eBay kits are not the same product; no fitment support, no warranty.
- Expectations: it improves distribution and noise, not BTU capacity — an undersized A/C is still undersized.
