Hi-draw chemical injector supplier

Good day to you all :slight_smile:

Can anyone point me to a quality high-draw chemical injector (20%) that ships to Australia? I’ve done numerous searches, but nobody seems to ship here :frowning:

I currently use one that says “2.1” on it, on a 4GPM/4000psi machine. I’m sure they said it draws 12% - but they had another there that said “1.8” on it. I just got the bigger one :open_mouth:

2.1 refers to size in mm. It is for a 3-5 gpm machine. That doesn’t help get one down under, but it’s a tidbit of info

Thank you IBS - I did wonder if I had the right one for the machine :+1:t2:

I’ve had a few high gutters that have needed stronger than what I’ve been able to throw recently. Hitting them two or even three times sprays the eaves and windows again unnecessarily.

Hopefully someone will be able to send me a 20% one from the U.S. Pressure washing is much more of an industry over there than here.

Try contacting Lori

Looking now - thanks!

If you have a smaller gpm machine, that will increase the draw, or should i say decrease the amount of water used, therefore more chemical.

Steve,

If you’re running that 2.1 on your 4gpm machine you’re pulling 9-1. If you pull stright SH you’re putting out over 1% already. that should clean just about anything. Going a tad stronger probably not going to help that much unless you switch to a 12vV or something similar or go the xjet route where you can get up to 3-4%. Going from 1.% to 1.3% probably not going to help that much

Ill send you my 1.8. Like you i bought a size down because of what i read on here. Like racer said using straight 12-16 SH on a 4k/4gpm will clean great on your normal hard to clean areas. If itd not working then you need a 12volt or xjet.

Thanks for all the replies/offers guys! Wow. Much appreciated.

Can I just get something clear in my head…

If my injector draws straight SH at 10%, then the rest is 90% water.

Meaning 10% is SH?

Your sh is a certain percentage to begin with. Around 12-15% for the strongest you can get from a commercial source. 4-10% from a retail store. Then you divide that by how much your injector dilutes it. Say your injector is 10-1 and you are feeding it straight 10% sh, it would be 1% sh.

Got ya. I was thinking more along the lines of when someone asks, how much chlorine is in the mix.

They don’t know about the actual concentration. 10% of it is chlorine (@13%) 90% is water.

I see everyone in here uses the same method of calculating it, so that’s all good - although it doesn’t make real sense to me :slight_smile:

Thanks for the info :+1:t2::+1:t2::+1:t2:

Update. Yes. Now it does make sense. Ha ha :wink:

My illustration assumes you are feeding your injector undiluted sh. Many techs will dilute it with water lowering the final solution even more.

I will note, I was thinking the same thing. 12.5% SH in a 10:1 injector was basically 1.25% hitting the house. However, @CaCO3Girl pointed out to me, you actually have 11 parts in that scenario so your percentage would be 1.136% hitting the house (12.5/11=1.136%). Not that big of a difference in a 10:1 scenario, but when your talking about a 3:1 it makes a lot more of a difference. Numbers confuse me sometimes, so I had a message discussion about it with her and she corrected me. Just wanted to point that out since the numbers can get a little off sometimes and I like to be as precise as possible. @CaCO3Girl if I am wrong, please correct me.
