Question:
I couldnt find any info as to whether the fan can function both as an exhaust as well as pull air in from outside. The older model 4000 did this, and I dont believe it is available anymore so I am looking for the next best thing. Thanks!

The MaxxFan # MA00A04301K you referred to isn't reversible, it will exhaust only.
If you want a reversible fan, you'd need to go with the MaxxFan Plus, part # MA00-04002K. This fan is reversible and can operate manually or by using the preset 78° thermostat.
The 4000K model is still available as part # MA00-04000K, it features a 10 speed fan, versus the 4 speed offered by the # MA00-04002K. I've linked to product description videos for both vent fans
