    Default Primers

    I have been spec'ing that primer on 90% of the new trucks I have quoted and sold for the last few years. Haven't had one complaint. Even had some clients that retrofitted older trucks after they had a chance to use the Trident. One thing you have to be sure to check is you have a large enough compressor and air storage. Most trucks I do we put and extra air tank on. A 18CFM compressor should do the trick.

    We had two of those on our rigs.The vanes over time get sticky and the primer quits working.What we did was pull the little plug out of the top,installed an oil tank,plumbed them up and now they're an oil type primer rather than the enviornmentally friendly oilless.The up side is they work,everytime,and you don't have to pull them apart every six months to free up the vanes.Hale can't sell you the kit but almost any fire mechanic worth his presence can make the conversion.Simple,inexpensive and effective. T.C.

    Funny you should mention that. In 1998 the rotary gear primer on our'78 Hahn, Hale QLD125 failed (a whole 'nother story). I replaced it with a Hale oilless primer. When it was new, if you didn't operate it at least every week, it would stick. After a couple of tries, it would break loose and work. Ever since then, it works fine. We have a dry hydrant that includes about 40' lateral and about a 20' lift. It pulls a prime from there every time, no sweat (annual practice). So simple, even FWDbuff can do it.

    Stay safe out there, everyone goes home!

    Default More TRIDENT info wanted

    So...does anyone have any more info about TRIDENT primer? How about Retrofit issues? Freezing issues? Clogging issues?

    Hale actually recommends you use and check the primer weekly. Part of that check is to flush water through it for 10-15 seconds. As the vanes turn, some of the carbon wears off and can collect in the primer and jam the vanes. Flushing them helps get rid of the carbon that collects. Perhaps that is part of your issue?

    I don't know about how much trouble it was, but a department I just sold a rig to had a Trident primer retrofit into an existing pumper. I didn't sell them that pumper nor was I involved in the install, but they're so tickled with the primer that we did a change order to put one on the rig they bought from me...

    My discussions with them made it sound like installing the Trident really wasn't that big of a deal. I think (it's been a while since we talked about it) that their mechanic did the install in their station in about a day.

    I don't suppose anyone would know round-about what one of these costs? We've got an older pumper that the primer has gone out on. Hale says it's an antiquated primer and there's no longer parts available. We really don't want to have to mess with spending $1,500 on a primer for a truck we rarely use. I'm curious if this Trident is a more cost-effective alternative.

    Catch,like I said Hale isn't allowed to tell you what I just did.And your book definition is spot on.However with our water and use conditions,we found that a oiless to oil conversion eliminated the problem. Entirely! No sticking,no screwups,and faster priming with less wear.Do you want a tuna with good taste or a tuna that tastes good? T.C.

    Talking Trident Air Prime

    I have this primer installed on the last 2 truck we have purchased, and retrofitted our other engine when the esp failed. We have had no problems with the primer at all. We will never go back to an electric.

    I understand what you're saying, and I'm not saying you're not right. Just throwing a thought out for a possible quick fix for a lot of guys. I'm sure you know as well as I do a lot of the fire service doesn't care for their equipment like they should.

    Do those Trident air primers work on under-the-hood sprinkler systems?

    Default retro-fit

    just to add a little more. we just got said truck retro-fitted with the trident unit. our test & drill with it seems very good. there is little noise compared to the electric units. and there is not a 300 amp draw on electrical system. as for another reply when we first had issues with esp unit a hale rep at factory told me that they hadn't had any complaints about the units and as a matter of fact it was the standard for most manufacturer's. at which time i told him ( politely ) i could tell him at least 2 other departments in a 10 mile radius that have had nothing but troubles as well. after the first rebuild they told us to just pull prime valve after pump had picked prime to flush out primer . it still didn't help. the only good thing is our neighboring department has rebuilt there's 4 times in 3 yrs. then last month after 2 rebuilds i talked to a rep and he sent me the info on converting esp to fluid. its an easy fix. in the info they say to install 2 tanks, 1 for the priming liquid and 1 for the expelled liquid. we discussed it at a meeting about what to do about not being able to trust the esp unit's reliability and decided to go with the trident. our repair shop gave us a few names of departments that had spec'd them on there new trucks and they all were very positive as being the way of the future. if it works out well on this unit it will be retro-fitted to our other engines in the future. sorry for the long post. stay safe. walt

    I'm pushing to add the Trident AirPrime™ for all our new trucks.

    One thing has me wondering though.....

    NFPA 1901 (2009) 24.12.1* states that the chassis air brake system shall not be used for emergency use applications.

    How do we get around that?

    I went to the appendix to get some details on the asterisk notation, and it states that the air brake system is not intended rescue air bags, air tools, air reels, and other rescue applications.

    I never understood this requirement when it was instituded since chassis air compressors usually have 100% duty cycle ratings. Air brakes fill a HP air bag like a champ.

    But if you specify an independent tank that is specifically for this purpose, and will not drain the air tanks used for braking, does this satisfy the requirements?

    You get around it by signing the contract before Jan 1! haha

    We specified the Hale ESP and said the Trident Air could be used as an alternative. After reading more and more about the Trident I hope the bidders propose that over the Hale. The air compressor is 18.7 cfm so that should be plenty.

    Unless your doing pump and roll operations I dont see how the air primer could be a concern with your brake system.

    I wasn't even aware of Trident until they came and made a presentation at our county engineers' association meeting a year or so ago. I was very impressed with its simplicity and there for inherent reliability. Its operating principle is very similar to that of an exhaust primer. If I had been aware of it when we spec'd our Toyne, I'd have asked the members to consider using it. I do get to go to Trident's facility and visit every now and again. Their location is such we'd probably be due there on a second alarm.

    Can someone throw some numbers out there about how much the retrofits cost?

    It may, I didn't look at it from that angle. I e-mailed Trident about it. We'll see when they reply.

    That requirement was part of the 2003 version as well. It's not new.

    If you have any concerns, call Trident. I spec'd the air prime on our new Kool-Aid pumpers but had questions about whether to spec larger tanks to supply the air needed for the primer. They put me straight through to their engineer that designed the airprime (sorry I don't remember his name) and he answered all of my questions promptly. He did state that any compressor on any custom chassis can keep up with the requirements and no additional tanks are necessarry on customs.

    We will take delivery of our first engine in January and I will try to let you know how it does. It seemed like a no-brainer for me. I was tired of burned up solenoids and motors so I felt that it was better to spend a little extra up front for the air prime

    I DID spec an extra tank with ours.Thought being that we have some long/high lifts and a little extra air helps the venturi work better longer. T.C.

    Got this e-mail from Trident today. They were very swift in their reply.

    Hi txgp17:

    Thanks for your excellent questions on the AirPrime in relation to the 1901 standard. Essentially there is nothing new between the year 2003 and 2009 standard with regard to our interpretation of how the AirPrime meets the standard.

    The application of the ENTIRE chapter 24 as defined in 24.1 is ONLY for breathing air systems and utility air systems. We do not run the AirPrime accessory from a breathing system or a utility air system. Rescue tool air applications DO require larger air flows and volumes and should be excluded from running off the air-brake air system.

    Rather we look at the chapter 12.3.1 requirements for air accessories such as air-horns, air suspension seats, AirPrime, etc. The requirement here is for a pressure protection valve which ensures that there will always be enough air pressure left in the tank to release the air-brakes and move the truck at any time if necessary. As you may have noticed from our literature we insist on a large enough air-compressor to keep up with the AirPrime requirements so that we can have the air-compressor “keep-up” by itself without relying on or depleting all of the air volume / pressure in the tanks.

    The AirPrime system has been available for about 5-years now, and nearly all OEM truck builders have installed at least one. Many OEMs have standardized on the AirPrime so they are also OK with interpreting the standard as I have described here. I served as an alternate on the 1901 committee prior to the 2003 standard and continue to attend all committee meetings as a task team member and the issue of someone trying to apply new chapter 24 (old 25) to the primer has NEVER come-up.

    I hope this information is helpful, and let me know if you need anything more at this point in order to feel comfortable or convince others that we do meet the intended requirements of the 1901 in full measure.
