3P207-AFC (certified for installation on all aircraft with de-ice boots) - Replaces all 400 Series Dry Pumps

Introducing the Airwolf 3P194-AFC wet pump, based on the universally accepted Pesco and Garwin pumps. Four thick, robust vanes are lubricated by a fine mist of engine oil for incredibly smooth, fracture-free operation. The pump is milled from a solid aluminum billet, and direction of rotation is unimportant, eliminating vane fractures. Combined with our top-selling oil filter system and genuine Walker AirSep your vacuum system finally becomes dependable.

Failure is not an option.
Q: What about the Rumors about dry-vacuum pump FAILURES?
A: They are ALL true.
Dry Vacuum pumps are the only accessories pilots talk about with inevitability - "when it fails". Not "if, but "when".
The vacuum pump is the most critical for IFR flight. Yet they consistently fail, often with fatal results.
Q: Why do dry pumps fail?
A: Since the 1970s, when cheaper dry pumps were introduced, they have been made with thin, brittle carbon vanes which usually break before 500 hours. Dirt in the line, solvents, water, reverse propeller rotation from backfiring or even backing the prop by hand - all can cause catastrophic disintegration of the vanes.

Lets analyze your options:

  1. Dry pumps. If they were any where near as reliable as their manufacturers claim them to be, you wouldn't be checking out your options.
  2. Precise Flight carb systems. First thing you must realize is that you are not going anywhere fast, if you have to use their solution. Their standby system requires greatly reduced power settings to create enough vacuum in the venturi of the fuel system to power the gyros. Therefore, you are definitely coming out of the sky, even if it is slowly. If that wasn't bad enough, if you have to shoot an instrument approach, you better pray that you make it the first time around. Otherwise the same time you are pouring the coals to engine to do a go around, you no longer have this reduced throttle condition to run your gyros and they will be spinning down during the missed approach. We cant think of a worse situation to have your gyros spooling down. And if this isn't enough, they have a reoccurring AD to contend with.
  3. Standby electric systems. They are expensive, [$1,500 or so] heavy, take up lots of real estate on the firewall and again are just an electric motor connected to yet another unreliable dry vacuum pump.
  4. Aero Advantage is out of business. Unfortunately some things that look good on paper don't work so well on actual airplanes. After experiencing multiple dual chamber failures on numerous aircraft with no solution in site, Aero Advantage has decided to close their doors and exit the business. This reaffirms our position that no amount of dry pumps can ever equal the proven reliability of a wet vacuum pump.
  5. The new Sigma Tek Aeon dry pump. A step in the right direction as it has no brittle graphite rotor and vanes. However only time will tell if it holds up. Unfortunately what looks good on paper, and performs well on a test stand, can be far different when actually bolted to an engine. So until this pump a lot of time put onto it on many different aircraft, there is no way of knowing if it is any more reliable than the current dry pumps.
  6. Airwolf Wet Vacuum Pumps are extremely reliable. Wet pumps have a proven track record with over 60 years of history. They are reasonably priced and the ultimate in safety & security. If you never, EVER, want to worry about another vacuum pump failure, this is the only way to go. This is the solution to the problem, not just another Band-aid on a symptom.

Let's Do The Math:

Average Cost of replacing a dry pump on your aircraft every 500 hours $500
Cost to replace 4 dry pumps, (assuming each pump lasts 500 hours) $2000
Cost of an Airwolf Wet Pump that will last 2000 hours $1599
Airwolf saves you + $400
