Looking closely at these two in the McH13/PE200 range.
Personal plus some friends and students, as my LW100 is too loud, too frantic and too slow.
Is it a no brainer to go for the PE200 at a 15% premium, or is that extra money Incan spend on a hop up kit, and extra cooling with the cheaper Coltri?
25-35 degrees ambient, so will be adding extra filtration and seperator to either, maybe later in a few years pump more, but for now, a few hours a week.....
How much better Is the Bauer block? Esp when not using continuously?
If your limiting yourself to comparing just these two models then IMHO
No brainer, just surprised so little more at 15% for the IK120 three stage block.
Neither models are the best for your hot climate application but given a choice between these two.
The box standard PE200TE with the P21 triplex filter but with a P41 or equivalent filter as an additional wall mounted stand alone filter unit.
Run both as re packable with after brand 316 stainless insert cartridges and a visual indicator set at 20/40/60% RE off the P21 and a second indicator 10/20/30% relative humidity off the P41 (note not the offered P42 filter)
The PE200TE runs Three stage 1250 RPM stages 1st and 2nd stage splash lubricated with the final 3rd stage using the new polymer rings (similar to a RIX SA-6 final stage) has a small low pressure 5bar oil pump and a bigger 2.6 litre oil sump. This is compared to the older 1.6 litre sump
To compensate for heat they fit a new designed "sickle" fan
The IK120 block weakness is the high blow by (25lpm) as opposed to the older block with less than half that.
The Coltri by comparison is a smaller pistoned block running faster 1350 RPM also 3 stage but only splash lubricated using oil throwers on 2nd and 3rd stage and a pitiful oil vapour lube tube for the 3rd stage
Neither of them give you the piston diameters or the rod stroke so you cant really make an engineering comparison. Also finding out the simple question of the oil sump capacity is also like looking for Hen's teeth as they both omit from the manuals.
Filtration length and diameter also critical information neither are willing to disclose
But from memory the Bauer is around 50% greater capacity and for that alone in a hot climate would be a factor.
I would discount the Coltri narrow tube filter as not being any way near close a contender for an adequate filter tower.
Also check out spare parts pricing and maintenance schedule with both brands before you pull the trigger so to speak.
To me at least its annoying that Coltri in there new online manual have removed both the oil capacity and piston diameters and go to great length with a plethora of unnecessary junk information yet take out the two critical items of info you need to make an informed choice. But hey ho out of the two options given we just made the choice easier for you I guess. Iain
