New Rain Bird Rotaries

Sorry, not trying take the thunder away from RB, I'm super happy they're FINALLY adding strips to their great lineup of rotaries. Hunter had already released their MP815 to zone with their current 800SR, is that coming along too?

Thanks

Cbillete,
Yes, these would fall into the same bucket.

In the meantime, the Hunter MP strip patterns have the same app rate as the RB rotaries. Plus, a 5' width (RB has 4').

Turns out that standard MP nozzles, strip patterns, and SR all have different app rates and should be circuited separately.

Bumping this up.... Just looked at RB's web site--their strip patterns are 5X, not 4X. So one can edit the Hunter version to say that they're RB strips. Be sure to select 45psi as the design pressure, since that's RB's default. The only thing I've found is that Hunter abbreviates with "LST" and "RST," which is what shows up in the schedule. RB useS LCS and RCS.

I know you guys are working on this!

Thanks!

I was thinking about this the other day and saw this was written that one could use the Hunter MP strips in the mean time for the RB strips. Only because I was asked to use RB's RD spray bodies with MP heads. So I thought, what if it was the other way (since I think Hunters spray bodies are mechanically better than RB's)

Initially I thought that RB's would emit more GPM like the RVANs. I was looking on RB's and Hunter's flow rates and they are very similar. However Hunter does not have precipitation rates for their MP Strips but noted that their percip-rates are matched (around 0.37 to 0.41). RB is 0.62 - Sooooo, its something to think about regarding application rates. To be on the safe side, I'd use the MP strips like Tom Lang mentioned, but zone them separate.

Precipitation Rate = 96.25 X Total GPM / Area

if they have a very similar flow rate, it is mathematically not possible for the precip rates to not be almost identical, given same pressure, area of coverage, and head to head spacing

Alrighty guys, the R-VAN corner and strip are available to use!

Craig is correct, the precip rate is straight forward and the two products are actually almost identical. The main thing to look at when comparing precip rates is the manufacturer test note. How is the nozzle laid out to get the result they speak of?

Apples to apples show only a .02 GPM difference between the two nozzles. The throw is also off by a difference of 1'. So, the ever so slightly higher GPM with the ever so slightly smaller throw of the RVAN means it will have a ever so slightly larger precip.

In either case, use what is best for the site! Go get em!
